43% AC PROBLEM 5: The crane shown supports a large wrecking ball of mass M on a cable of length L = 16.5 m. The trussed beam of the crane can be approximated as a uniform beam of mass 460 kg, and the two supporting cables (those attached to the top of the crane's cab) can each have a maximum tension of 55 kN. Assume that all cables and the beam are coplanar. (a) Find the maximum wrecking ball mass that the crane can support. (b) Assume that the wrecking ball can act as a simple pendulum. Find expressions for the position, velocity, and acceleration of the pendulum as a function of time. For this part, fill in your expressions with numerical values as much as possible.

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.
