In adjacent figure Pulley p1 is fixed and Pulley P2 is movable if w 1 = w 2 = 100 Newton ,what is the angle A p2p1? the pulleys are frictionless:

Question

Venkat · Answer

Assume tension in string AP 2 and P 2 P 1 as T. Balance the force on pulley P 1 → T =W 1 Let the angle AP 2 P 1 be 2 theta. consider forces on P 2 2Tcos(theta) = W 2 2W 1 cos(theta) = W 2 As weights are same -->cos(theta)=1/2 → theta = 60 degrees So angle AP 2 P 1 is = 2 x 60 =120 degrees Option (4)...
