Electric motor

  1. Jun 8, 2005 #1
    Two people carry a heavy electric motor by placing it on a light board of length 2.50 m. One person lifts at one end with a force of 400 N, and the other lifts the opposite end with a force of 560 N.

    a) What is the weight of the motor?
    b) Where along the board is its center of gravity located? Express your answer as a distance measured from the end where the 400 force is applied.

    ** I know that each force times its distance to the center of mass gives the same product (the moments are equal) but don't know how to do this problem.
