A gymnast with a mass of 54 kg stands on the end of a uniform balance beam as shown in the figure. The beam is 5.00 m long and has a mass of 250 kg. Each support is 0.54m from the end of the beam. What is the force on the beam due to support 2?

  1. Support 2 is at the other end and the gymnast is supposed to be over support 2

  2. I am going to assume the gymnast is standing on the end, not over the support2. Otherwise this is trivial.

    moments about support 1

    2.5 - .54 = 1.96 from middle to support

    250(1.96) + 54(2.5+1.96) = F2 (2*1.96)
