STEP 6: Position of 15 kg mass = Torque due to 15 kg mass = A Position of 15 kg mass = Torque due to 15 kg mass = B Position of 1D kg mass = Torque due to 1G kg mass = C Position of 2D kg mass = Torque due to 213 kg mass = D Sum of torques = A+B+C+D Added mass Position of 2D kg mass = Torque due to 20 kg mass = E Sum of torques due to all FIVE masses = A+B+C+D +
