1. The problem statement, all variables and given/known data A gymnast with mass m1 = 46 kg is on a balance beam that sits on (but is not attached to) two supports. The beam has a mass m2 = 118 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. What is the force the left support exerts on the beam? 2. Relevant equations Sum of Torques = 0 Sum of Forces = 0 F = ma T = rf 3. The attempt at a solution I set the second beam as the axis of rotation since that is an unknown quantity. m1 = man m2 = beam N1 = first support N2 = second support The equations I got are: m1*g + m2*g - N1 - N2 = 0 -2L*m1*g/3 + LN1/3 - L*m2g/6 = 0 Using the second equation, I solved for N1 = 2Lm1g+Lm2g/2 = 7406.55 which is wrong What am I doing wrong?
