Torque of bolted beam

  1. Dec 1, 2005 #1
    hey could someone please help me to check if i did this correctly and got the right answer please? thanks

    A 4m long, 500kg steel beam extends horizontally from the point where it is bolted to the framework of a building. a 70 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?

    i used t=r x F

    2(500)(9.8) + 4(70)(9.8)

    my result came out to be 12,544 N m....

    i am not sure if this is correct or not. thanks.
