SUMMARY
The upward force in a lever system can be calculated using the principles of torque. In the given scenario, the thigh muscle generates a force of 400N at a distance of 2cm from the fulcrum, while the weight is positioned 40cm from the fulcrum. The torque produced by the muscle must equal the torque produced by the weight for the system to be in equilibrium. Therefore, the upward force can be determined using the formula: Torque = Force x Distance.
