To measure the angle of elevation of a building, one must use a clinometer by looking through it to see the top of the building, rotating the protractor inside to bring it into view, and recording the angle measurement on the clinometer scale. This angle is the elevation. The clinometer height and distance to the building should also be measured from multiple locations to gather additional elevation angle data points.

Clinometer by Vinod Thombre - Patil
Clinometers are used in many professions to measure slopes and inclines. Geologists, surveyors, skiers, sailors, and cave surveyors use clinometers to measure heights, slopes, cloud heights, and map underground cave systems. City planners also use clinometers to ensure that roads and sidewalks do not exceed a 10% gradient, as steeper slopes can be dangerous and increase pollution from vehicles. The document provides examples of how clinometers are used in various fields and describes an activity where students measure hill gradients to determine if roads should be built.
Clinometer
An inclinometer or clinometer is an instrument used to measure angles of slope or tilt with respect to gravity. Foresters use clinometers and basic trigonometry to measure the height and slope of trees. They stand at a fixed distance from the tree and measure the angle to the top and bottom to calculate the total height. Clinometers are also used to measure terrain slopes and are applied in surveying, safety systems, monitoring movements, and adjusting equipment angles.

Nspire--iPadAppTutorial--Quadratic Functions Standard Form with Sliders
This tutorial explores a quadratic function in standard form (y = ax^2 + bx + c) using sliders on the TI-Nspire app. It creates a graph window, inserts three sliders to control the values of a, b, and c, links the sliders to the quadratic function, and allows manipulating the sliders to update the graph.
Step by step using a total station
Setting up the total station involves choosing target locations and mounting the total station and prisms onto tripods at those locations. The total station must then be leveled using foot screws to align the bullseye bubble at the center. Once mounted and leveled, the total station is positioned to face the prism and the cross hairs and image are focused using the focus rings. Angles are then measured by setting the current position to 0 degrees when facing the desired prism, and checked by flipping the total station to 180 degrees and realigning with the same prism.
Deflection angle ppt
The document discusses angular vector forces that occur when ropes pass through directional pulleys. It provides examples of different deflection angles and the percentage of load weight applied to the directional pulley anchor point. At a deflection angle of 20 degrees, 34% of the load weight is applied. At 45 degrees it is 76% and at 60 degrees it is 100%. A deflection angle of 90 degrees results in 141% of the load weight applied to the anchor point. The document states that angular vector forces can be calculated using mathematical formulas.

This document discusses axis signal correction in trigonometric leveling. It defines axis signal correction as correcting observed vertical angles due to differences in instrument and signal heights. It then derives the formula for axis signal correction as the difference between the signal and instrument heights divided by the horizontal distance, which corrects the observed vertical angle. The conclusion is that axis signal correction adjusts observations for non-equal instrument and signal heights.
BASIC VECTOR NOTES
This document discusses vector quantities and how to represent and calculate them graphically. It defines scalars as quantities with only magnitude, and vectors as quantities with both magnitude and direction. Vectors can be represented by arrows on a line, with length showing magnitude and direction showing direction. Two common graphical methods for adding vectors are explained: the triangle/nose-to-tail method, where the second vector is drawn from the tail of the first; and the parallelogram method, where vectors are represented as sides of a parallelogram and the resultant is the diagonal. Examples of using these methods to calculate the magnitude and direction of resultant forces and velocities are provided.

Trigonometric leveling 01
Trigonometric leveling is a surveying method to determine vertical distances between two points by taking vertical angle measurements and known distances. It accounts for refraction and curvature of the Earth. Refraction makes points appear higher, while curvature makes them appear lower, so their combined effect is that points appear lower. Refraction corrections are negative for elevation angles and positive for depression angles. Curvature corrections are positive for elevations and negative for depressions. The total corrections combine these and consider the distance between points, Earth's radius, and coefficient of refraction.
Comparing quadrilaterals to kite - viii e
This document compares and contrasts different types of quadrilaterals to a kite. It defines trapezoids, kites, parallelograms, rectangles, squares, and rhombuses.

For example, to make a trapezoid a kite, opposite sides must be made equal length and opposite angles must be made equal. Finally, it concludes that squares and rhombuses have the exact same properties as kites, so they are special types of kites.

A projectile is any object projected by some means that continues to move due to its own inertia. Projectiles move in two dimensions with both horizontal and vertical velocity components. The horizontal velocity is constant, while the vertical velocity changes due to gravity. Together the components produce the trajectory path, which is parabolic. For horizontally launched projectiles with no initial vertical velocity, the horizontal velocity remains constant while the vertical acceleration is due to gravity. For vertically launched projectiles, the total velocity must be broken into horizontal and vertical components using trigonometry. The kinematic equations can then be applied to each component to solve for time, displacement, or other variables.Projectile Motion || Grade 9 Physics || K to 12 Science
This presentation includes a description of the horizontal and vertical components of projectile motion.
