Directions: Show your solutions explicitly, i.e., do not just write the final answer. Always simplify your final answer. Write legibly in engineering lettering. Problem I. In a high-rise building construction, a boom is being used to efficiently transport materials from the ground to a certain level in the building. Shown below is a figure of the boom supporting the load 'P.'
