A 5.00m long, 470 kg steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 69.0kg 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?

1 Answer

  • T = 470 9.8 (5/2) + 60(9.8)(5)

    T = 9.8*5[(470/2) + 300]

    T = 26,215 N-m.

    Hope this helps.
