Question

The uniform rod AB of mass m is released from rest
when B=60º. Assuming that the frictional force between
end A and the surface is large enough to prevent sliding,
determine (for the instant just after release)
B

(A) the angular acceleration of the rod,
(B) the normal reaction and the friction force at A,
(C) the minimum value of u, compatible with the
described motion.​

Answer 1

Answer:

(B) the normal reaction and the friction force at A,is correct option thanx
