The mathematics of vectors is quite different from the mathematics of scalar quantities. For Example, in the multiplication of scalar quantities we use the “dot product”, whereas in the multiplication of vector quantities we use the “cross product” or the vector product method to account for direction.

Free body diagram
Free body diagrams show the relative magnitude and direction of all forces acting on an object. They include only physical forces touching the object like gravity, applied forces, friction, and reactions, drawn as arrows from a dot representing the object. To analyze motion, forces are resolved into horizontal and vertical components and Newton's second law is applied to each direction separately. For example, with an applied force at an angle on a block, the horizontal force component gives acceleration along the plane while the vertical forces sum to zero for no jump.
Moment
The document discusses moments, which are the tendency of a force to cause rotation about an axis. It defines key terms like moment, moment arm, and how to calculate moment using the equation: Moment = Force x Perpendicular Distance. It also covers units of moment, properties like sense of direction, and applications like Varignon's theorem for resolving forces. An example problem is worked through to find the moment created by different forces and placements.
Equilibrium and Equation of Equilibrium:2D
This presentation discusses the concept of equilibrium in 2 dimensions. Equilibrium occurs when the net force and net torque on an object are both zero. This allows the object to remain at rest or in uniform motion. The key equations of equilibrium in 2D are: the sum of the horizontal forces equals 0 (ΣFx=0), the sum of the vertical forces equals 0 (ΣFy=0), and the sum of torques about the z-axis equals 0 (ΣMz=0). Examples are provided to demonstrate how to apply these equations to solve for unknown forces by drawing a free body diagram and setting up the appropriate equilibrium equations.
LAWS FOR THE RESULTANT FORCE
The document outlines two laws for finding the resultant force of a system of forces: 1) the triangle law of forces which states that the resultant of two forces can be represented by the third side of a triangle formed by the other two forces, and 2) the polygon law of forces, an extension of the triangle law to more than two forces, where the resultant is the closing side of a polygon formed by the other forces. It also mentions the graphical/vector method for finding the resultant force which involves constructing a diagram showing the magnitude and lines of action of the individual forces.
Lami's Theorem | Mechanical Engineering
If two or more than two forces are acting on a single point then the forces are known as system of concurrent forces and if they are acting on a single plane then the forces are called as coplanar forces.

This document contains a student's acknowledgements and summary of basic mechanics concepts including: statics, dynamics, kinematics, kinetics, hydromechanics, hydrostatics, hydrodynamics, the parallelogram law of forces, Lami's theorem, resultants of force systems, and resolving forces into components. The student thanks God, their teacher, parents, and friends for their support and contributions to completing their project.
Centroid & Centre of Gravity
The document discusses the differences between centroid and center of gravity. The centroid is defined as a point about which the entire line, area or volume is assumed to be concentrated, and is related to the distribution of length, area and volume. The center of gravity is defined as the point about which the entire weight of an object is assumed to be concentrated, also known as the center of mass, and is related to the distribution of mass. Examples are provided to illustrate the concepts of centroid and center of gravity.

Couple 136
This presentation defines a couple as a system of two parallel forces that are equal in magnitude but opposite in direction and separated by a perpendicular distance. It provides the expression for calculating the magnitude of a couple as the product of one of the forces and the perpendicular distance between them. Some key properties discussed are that a couple produces rotational but not translational movement and has a resultant moment but not force. Examples of how couples apply to reinforced and pre-stressed concrete are also provided.
Rigid body
Statics is the study of rigid bodies at rest or stationary. For a rigid body to be stationary, it must be in equilibrium, meaning there are no unbalanced forces acting on it. A force is a push or pull that one body exerts on another and has magnitude, direction, and point of application. A moment is the tendency of a force to cause rotation about a pivot point and has units of length-force. Any system of forces and moments can be represented as a single resultant force and moment. For an object to be static, the resultant force and moment vectors acting on it must both be zero.

1) The dq0 transformation represents the synchronous machine model by transforming the stator and rotor variables from the stationary abc frame to the rotating dq0 reference frame.
2) This allows the machine equations to be expressed with constant inductances instead of inductances that vary sinusoidally with rotor position.
3) The transformation involves applying Park's transformation matrix to the stator and rotor phase variables to obtain their corresponding dq0 components, resulting in a simplified machine model with decoupled d- and q-axis circuits.
Fundamental of Statics (Part 1)
Okay, let's solve this step-by-step:
* P = 100 kN
* Angle between P and Q (θ) = 90°
* Cos 90° = 0
* Using the parallelogram law:
* R2 = P2 + Q2 + 2PQcosθ
* R2 = P2 + Q2 (since cos90° = 0)
* R2 = 10000 + Q2
* R = 100 kN
* Therefore, Q2 = R2 - P2
* Q2 = 10000 - 10000
* Q2 = 0
* Q = 0 kN
So if the two forces act at right angles to each other, and

3). work & energy (finished)
1) Work is defined as the product of the force applied and the distance moved in the direction of the force. Work can cause a change in energy but the total energy in a system remains constant.
2) There are four types of work depending on whether the force and/or distance is constant or variable. Work by a conservative force depends only on the start and end points and not the path taken.
3) Kinetic energy is the energy of motion while potential energy is stored energy due to an object's position or state. Mechanical energy is the sum of an object's kinetic and potential energies.

This document discusses parallel transport of tensors along curves in curved spacetime. It shows that for parallel transport where the covariant derivative of the tensor equals zero along the curve, the tensor components must change as it is parallel transported due to the connection coefficients (Christoffel symbols). This ensures that the tensor remains tangent to the curve at each point and that the dot product is preserved under parallel transport along the curve. It also notes that parallel transport equations relate the tensor transformation rules between coordinate systems through the proper speeds along the curve.
Trignometryppt
Trigonometry is the study of relationships between sides and angles of triangles. It was originally developed to solve geometric problems involving triangles. Today, trigonometry has many applications in fields like electrical engineering, physics, navigation, construction and more. The document discusses key concepts in trigonometry including defining angles using radians and degrees, trigonometric functions like sine, cosine and tangent, and important trigonometric identities.
AJMS_482_23.pdf
The document summarizes research on using various iterative schemes to solve fixed-point problems and inequalities involving self-mappings and contractions in Banach spaces. It defines concepts like non-expansive mappings, mean non-expansive mappings, and rates of convergence. The paper presents two theorems: 1) an iterative scheme for a sequence involving a self-mapping T is shown to converge to a fixed point of T, and 2) an iterative process involving a self-contraction mapping T is defined and shown to converge. Limiting cases are considered to prove convergence as the number of iterations approaches infinity.
Motion in a plane
This document discusses vectors and their properties. It provides examples of vector addition and multiplication. Some key points:
- Vectors have both magnitude and direction, while scalars only have magnitude. Vector addition follows the triangle and parallelogram laws.
- There are two types of vector multiplication: the dot product, which results in a scalar, and the cross product, which results in another vector.
- The dot product of two vectors is equal to their magnitudes multiplied by the cosine of the angle between them. It is used to calculate quantities like work and power.
- Vectors can be resolved into rectangular components using a set of base vectors like the i, j, k unit vectors. The magnitude

Managerial Hubris | Finance
The document discusses the concept of managerial hubris, which refers to excessive pride or self-confidence held by senior managers that can lead to cognitive biases and poor decision making. Managerial hubris can result in empire building within an organization as managers seek to expand their power and influence. It is also related to mergers and acquisitions if acquiring company managers overestimate their ability to manage target companies. This can lead to winners' curse, where the winning bid exceeds the true value of the target. The hubris hypothesis suggests managerial hubris in acquisitions can result in bids over the intrinsic value and ultimately lower shareholder returns.
