Question

A cylinder of weight w is resting on a fixed V-groove as shown in figure.Calculate normal reactions between the cylinder and two inclined walls.

(A) w,w 

(B) w/2,w/2

(C) w,w/2 

(D) w/2,w

Answer 1

(A) Normal reactions between the cylinder and two inclined walls is w,w. 

Explanation:

The figure shows how the normal forces are acting on the contact points of the cylinder and inclined wall. 

After resolving the force we find, 2×N×sin30 = W or N = W
