Question

Determine the minimum force P to prevent the 30 kg uniform rod AB from sliding. The contact surface at B is smooth, whereas the coefficient of static friction between the rod and the wall at A is μs= 0.3.

Answer 1

Answer:

88.2N

Explanation:

Coefficient of static friction = force (P)/(mass × acceleration due to gravity)

Force (P) = coefficient of static friction × mass × acceleration due to gravity = 0.3 × 30 × 9.8 = 88.2N
