1. The problem statement, all variables and given/known data A gymnast with mass m1 = 48 kg is on a balance beam that sits on (but is not attached to) two supports. The beam has a mass m2 = 119 kg and length L = 5 m. Each support is 1/3 of the way from each end. Initially the gymnast stands at the left end of the beam. Now the gymnast (not holding any additional mass) walks directly above the right support. Q1:What is the force the left support exerts on the beam? Q2:What is the force the right support exerts on the beam? 2. Relevant equations [itex]\Sigma[/itex]F=0 τ=0 3. The attempt at a solution For q1 I have used m1*g+m2*g - 3(m1+m2/2)*g is this correct? For q2 is 3(m1+m2/2)*g is this correct?
