Orthographic Projections

Orthographic projection is a technique where the object is projected onto planes perpendicular to the lines of sight to create 2D views from the front, side, and top. It shows the object as it would look from those directions. The views are positioned according to first or third angle projection rules. Dimensions and other details are included to fully specify the geometry and tolerances of the object being designed. Standard drawing sheet sizes, scales, line types, dimensioning methods, and title block contents are used to create technical drawings based on orthographic projections.

Types of projections

This document discusses different types of projections used in engineering drawings. It describes parallel projections where lines never intersect and perspective projections where lines converge at a point. The main types of projections discussed are:
- Orthographic projections where lines are perpendicular to the view plane. Multiview drawings use multiple orthographic projections.
- Axonometric projections including isometric, dimetric, and trimetric which rotate the object along axes.
- Oblique projections draw faces at arbitrary angles rather than 90 degrees. Specific types are cavalier and cabinet.
- Perspective projections make distant objects look smaller to provide a realistic view, with one-point, two-point, and three-point varieties.

Types of dimensioning

The document discusses four main types of dimensioning systems: 1) Chain dimensioning where dimensions are placed directly adjacent without gaps, 2) Parallel dimensioning where dimensions are measured from a common feature and shown parallel, 3) Superimposed dimensioning which simplifies parallel dimensions by using a small circle to indicate the common origin, and 4) Combined dimensioning which is a combination of parallel and other dimensioning types where dimensions are arranged in a straight line.

The document discusses isometric projection and how to create isometric drawings. Some key points:
- Isometric projection shows all three dimensions of an object simultaneously and at equal angles. Lines parallel to the three axes appear foreshortened to 3/4 of their true length.
- To create an isometric drawing, define three axes at 120 degree angles and draw construction lines. Then add object details starting from the front face, using techniques like box construction for non-isometric lines.
- Irregular surfaces, circles and curves require approximating techniques in isometric drawings since true sizes are not preserved. Four-point ellipses can approximate circles on angled planes.

This document provides information on isometric projection and isometric drawing. It defines isometric projection as a type of axonometric projection where all three axes are equally scaled at 120 degrees. Isometric drawings can be created using the box method, which involves sketching an imaginary box around the object and then removing volumes to draw the details. Key steps include positioning isometric axes, sketching the enclosing box, adding details while measuring on the axes, and darkening visible lines. Non-isometric lines that do not run parallel to the axes must be drawn using coordinate points on isometric lines. Circles appear as ellipses in isometric drawings and can be drawn using the four-center method.

An isometric drawing is a type of pictorial drawing that makes a three-dimensional object easier to visualize. It is constructed using a 30x60 degree triangle with the height, width, and depth all on a single plane. To make an isometric drawing, construction lines are first drawn at 120 degrees, then the width, height, and depth are measured along these axes before drawing parallel lines and adding detail. Circles and arcs can also be approximated using this method by first drawing a square based on the diameter and connecting points.

Emt capacitors

- A capacitor is an electronic component that stores charge and consists of two conducting surfaces separated by an insulating material. It is used for time delays, filtering, and tuned circuits.
- Capacitors come in sandwich or Swiss roll constructions with metal plates separated by an insulating material. The capacitance is determined by the dielectric material and plate separation distance.
- Capacitance is defined as the amount of charge stored per applied voltage. It is measured in Farads. The energy stored in a capacitor is equal to one-half the capacitance times the square of the applied voltage.

Led blinker

This circuit allows two LEDs to blink alternately using two transistors, capacitors, resistors, and diodes. When the battery is connected, the capacitors begin to charge through the diodes and base resistors. One transistor will turn on before the other, pulling its LED cathode to ground and lighting it. The opposite capacitor then discharges through its diode, turning on the other transistor and lighting the second LED. The capacitors alternate discharging through the diodes, causing the transistors to alternate turning on and off, making the LEDs blink one after the other. Changing the capacitor values changes the blinking timing sequence. Potential applications include railroad crossing signals, bike safety blinkers, and Christmas decorations.

Led ppt vgec ec engineering

LEDs (light emitting diodes) emit light when operated in a forward biased direction. They are made of a PN junction of n-type and p-type semiconductors. When forward biased, electrons in the n-side are excited across the junction and combine with holes in the p-side, emitting photons. LEDs convert electrical energy directly to light and are used as indicator lights and in various applications like mobile phones, cameras, displays due to benefits like energy savings and durability. The document discusses the working, types, applications and benefits of LEDs.

Electrical safety potection

This document discusses various electrical safety topics such as grounding, overcurrent protection, GFCIs, proper power strip usage, bonding and grounding, and an example of electrocution due to improper equipment usage. Grounding reduces shock risk by providing an alternative current path back to the source in case of a fault. Fuses and circuit breakers protect against overheating from too much current, while GFCIs quickly shut off power if any current leaves the circuit. Power strips should only be used for electronics and not overloaded or combined with extension cords. Proper bonding and grounding of all surfaces protects against static electricity dangers. The example incident describes a fatal electrocution that occurred due to a combination of unsafe factors including using

Led physics

Light-emitting diodes (LEDs) are semiconductors that emit light when electrically biased in the forward direction. LEDs come in various colors like red, blue, green, and white. They function by converting electrical energy to light energy and are used as indicator lights. The brightness of an LED is controlled by regulating the current through it using a series resistor. Too little current and the LED will be dim or off, too much and it can be destroyed. LEDs have a specific forward voltage and maximum current rating. When forward biased above the voltage, electrons combine with holes in the semiconductor, emitting photons that produce the light.

Agricultural Profitability through Resilience: Smallholder Farmers' Strategie...

This study investigated the knowledge strategies and coping utilized by smallholder farmers in Guimba, Nueva Ecija to reduce and adjust to the effects of climate change. Smallholder farmers, who are frequently susceptible to climate change, utilize various traditional and innovative methods to strengthen their ability to withstand and recover from these consequences. Based on the results of this study, farmers in Guimba, Nueva Ecija demonstrate a profound comprehension of the adverse weather conditions, such as typhoons, droughts, and excessive rainfall, which they ascribe to climate change. While they have a fundamental understanding of climate change and its effects, their knowledge of scientific intricacies is restricted, indicating a need for information that is particular to the context. Although farmers possess knowledge about climate change, they are not actively engaging in proactive actions to adapt to it. Instead, they rely on reactive coping mechanisms. This highlights the necessity for targeted educational and communicative endeavors to promote the acceptance and implementation of approaches. Furthermore, the absence of available resources poses a significant barrier to achieving successful adaptation, highlighting the importance of pushing for inexpensive and feasible measures for adaptation. Farmers recognize the benefits of agroforestry and have started integrating the growth of fruit trees, particularly mangoes, into their coping techniques.

Developing a Genetic Algorithm Based Daily Calorie Recommendation System for ...AIRCC Publishing Corporation

Lately, there has been an increasing fascination with employing genetic algorithms (GAs) to tackle
intricate optimization issues. Genetic algorithms (GAs) draw inspiration from natural selection and have
demonstrated efficacy in discovering optimal solutions for many problems, such as diet optimization. This
research presents a genetic algorithm (GA) approach to estimate individuals' optimal daily calorie
intake. The proposed approach considers the individual's age, gender, height, weight, exercise level, and
dietary limitations. In addition, it considers the nutritional composition of various dietary items. The
strategy aims to create a daily meal plan that fulfils the individual's calorie requirements and supplies all
necessary nutrients. The suggested technique was assessed using a dataset consisting of 100 people. The
findings demonstrated that the approach successfully produced dietary regimens that satisfied the
individual's specific caloric requirements and encompassed all vital elements. The technique also
produced diverse and captivating food menus. Additionally, we recommend a fitness function that
assesses each suggestion's appropriateness for a given user. Ultimately, to completely comprehend the
characteristics and functionality of our system, we conducted experimental reUpdated Limitations of Simplified Methods for Evaluating the Potential for Li...

- 2. Isometric Projection • Isometric projection is a method for visually representing three-dimensional objects in two dimensions in technical and engineering drawings. It is an axonometric projection in which the three coordinate axes appear equally foreshortened and the angles between any two of them are 120 degrees.
- 3. Isometric Terminology • The three coordinate axes are called isometric axes • Any line parallel to isometric axes is called isometric line • A non-isometric line is a line not parallel to any one of the three isometric axis • In isometric projection of cube, the faces of the cube and any plane parallel to them is called isometric planes
- 4. Isometric Scale • True lengths of the edges of the object are equally foreshortened • Correct isometric projection can be drawn using an isometric scale (always smaller than ordinary scale)
- 5. Isometric Drawing • Isometric Projection: Drawing prepared with isometric scale on isometric axes Isometric Drawing: Drawing prepared with ordinary scale on isometric axes
- 6. Steps for construction of Isometric : Step 1 Isometric sketches begin with defining isometric axes, three lines, one vertical and two drawn at 30° from the horizontal.
- 7. Step 2 Three lines of the isometric axes represent the three primary dimensions of the object: width, height, and depth
- 8. Step 3 Draw the rest of the isometric block.
- 9. Step 4 Add details to the block starting from the front face. Then add details to the other faces.
- 10. Step 5 Darken all visible lines to complete the isometric sketch. (make sure that construction lines are light)
- 11. • Axonometric projection shows all 3 dimensions, length, width and height. • The isometric lines are only drawn to scale. Objects composed entirely of isometric lines can be drawn by taking all measurements parallel to main edges of the enclosing box. • Non-isometric lines are drawn by transferring the ordinates (which are on isometric lines) of the end of the lines • Inclined and oblique surfaces are drawn using end coordinates. Box construction and offset measurements are common methods • In an isometric drawing, an angle never appears in its true size. Angles, irregular curves require special techniques
- 12. Objects with Normal Surfaces Make an Isometric Drawing with corner A at the bottom
- 14. Objects with Oblique Surfaces • Make an Isometric Drawing with corner A at the bottom
- 16. Objects with Non-isometric Lines • Make an Isometric Drawing with apex A facing front
- 17. Non-isometric lines are drawn with box construction and offset measurements Non-isometric lines are not drawn in true length in isometric drawing (BA is shorter than CA in this drawing)
- 18. Irregular Objects • Make an Isometric Drawing of the following irregular object (pyramid)
- 19. • OA and OB offsets help to locate apex O • Complete box construction may not be needed in each case
- 20. Objects with Circular Geometry •A circle in a orthographic projection will appear as an ellipse in an isometric drawing. •Instead of actual ellipses often approximate ellipses are drawn for isometric drawing. •Four-centre ellipses are used to approximate ellipses on isometric planes. How to draw four-centre ellipse???
- 21. •Draw the isometric centre lines of the circle. Using the centre lines, draw an isometric square with sides equal to the diameter of the circle. •From the near corners of the box, draw two large arcs with radius R, using the two red points as centres. •Draw the two smaller arcs with radius r, using two green points as centres.
- 22. Cylinder
- 23. Objects with Circular Geometry
- 24. Objects with Non-Circular Curved Surfaces • Make an Isometric Drawing of the following curved object
- 25. •A line that appears as a noncircular curve in a normal orthographic view of an object appears as a non-isometric line in an isometric drawing. •Curves may be drawn using a series of points by measuring along the normal lines in the orthographic view (offset measurements) and transferring these points on isometric drawing. Accuracy increases with number of points.
