A steel wire can withstand a load up to 2940 N. A load of 150 kg is suspended from a rigid support. The maximum angle through which the wire can be displaced from the mean (vertical) position, so that the wire does not break when the load passes through the position of equilibrium, is

Answer: (B)

Solution

For a pendulum released from rest at angle θ₀ from the vertical, the string tension at the lowest point (θ=0) is T = mg(3
