Question: A rigid bar AB having mass M = 1.0 kg and length L = 0.5 m is hinged at end A and supported at end

A rigid bar AB having mass M = 1.0 kg and length L = 0.5 m is hinged at end A and supported at end B by a nylon cord BC (see figure). The cord has cross-sectional area A = 30 mm2, length b = 0.25 m, and modulus of elasticity E = 2.1 GPa.
If the bar is raised to its maximum height and then released, what is the maximum stress in the cord?
