A 4.0-m-long 500 kg steel beam extends horizontally from the point where it has been attached to a building that is under construction. A 65 kg construction worker is standing at the far end of the beam.

A. Sketch the situation, label variables and centers of gravity. Collect known quantities.

B. Where is the center of gravity of the beam?

C. What is the gravitational torque on the connection point if no one is standing on the beam?

D. What is the total gravitational torque of the beam and the worker on the connection point?
