Problem
A 40 kg mass, hanging at the end of a rope of length l , oscillates in a vertical plane with an angular amplitude θ0 . What is the tension in the rope when it makes an angle θ with the vertical? If the breaking strength of the rope is 80 kg, what is the maximum amplitude with which the mass can oscillate without the rope breaking?
