Question:
In the pulley -powered weight dangler pictured below, a cable is attached to the structure at E', passes around a frictionless pulley of diameter 0.8 m at A, and is attached to a 1000 N weight, W . Tha member BFG is at a 45-degree angle, and that the constraint at G is a smooth, frictionless surface.
Find the magnitudes of all forces acting on member ABCD .That all appropriate free body diagrams must be completed for full credit.
Reaction force:
When an amount of force act on an object then it has the tendency to change the state of the object from rest to the motion, so a force which acts in the opposite direction to the applied force so that the member can remain in equilibrium is known as the reaction force.
