Question

A 4.60-m-long, 580 kg steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 72.0 kg construction worker stands at the far end of the beam. What is the magnitude of the torque about the point where the beam is bolted into place? In N*m

Answer 1

Multiply the forces and the lever arms (measured from the bolted place) for each applied force, and add them up. We will check you work if you will show it. The weight of the beam is applied at the middle

Answer 2

550*74+4.6*2.3

Answer 3

1723.2 Nm
