Question
A 3.10-m-long, 340kg steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 65.0kgconstruction 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? A 3.10-m-long, 340kg steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 65.0kgconstruction 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?Explanation / Answer
Torque = MgL/2 + mgL
= 340*9.8*3.10/2 + 65*9.8*3.10
= 7139.3 N.m
