Question

You injure your back at work lifting a 420-N radiator. To understand how it happened, you model your back as a weightless beam (the figure below), analogous to the backbone of a person in a bent position when lifting an object.

A. Determine the tension force that the horizontal cable exerts on the beam (which is analogous to the force the back muscle exerts on the backbone).

B. Determine the magnitude of the force that the wall exerts on the beam at the hinge (which is analogous to the force that a disk in the lower back exerts on the backbone).

C. Determine the direction of the force (measured from the positive x -axis) that the wall exerts on the beam at the hinge (which is analogous to the force that a disk in the lower back exerts on the backbone).

Explanation / Answer

please give the diagram of the question, i will answer your question in the comments once i get the diagram.
