Types of loading

In mechanical terminology, the term load indicates that external force/weight, either constant or variable, acts on a mechanical member/structure. The weight of an object of a specific material is also an external load, and the external force that works …

Expert Solution

Step 1: given and

force acting along AB= 315 N

let there are 3 cartesian axes x y and z

vertical axis=y

horizontal =x

perpendicular to the system is =z
