The vectors can be solved by Law of sine and law of cosines (two forces) Graphically Equilibrium Table Sum of values

1. Point loads - concentrated forces exerted at point or location 2. Distributed loads - a force applied along a length or over an ...

The principle of transmissibility states that the condition of equilibrium or of motion of a rigid body will remain unchanged if a force F...

Scalar Quantity has magnitude only (not direction) and can be indicated by a point on a scale. Examples are temperature, mass, time and d...

Consider two intersecting planes P1 andP2 with each containing a couple  Resultants of the vectors also form a couple  By...

Two forces F and -F having the same magnitude, parallel lines of action, and opposite sense are said to form a couple.  Moment of the...

A concurrent force system contains forces whose lines-of action meet at some one point. Forces may be tensile (pulling). Forces may ...

Block of weight W placed on horizontal surface. Forces acting on block are its weight and reaction of surface N.  Small horizontal for...

In preceding lectures, it was assumed that surfaces in contact were either frictionless (surfaces could move freely with respect to each ...
