The maximum mass m that a person can hold in a hand when the arm is positioned with a 105° angle at the elbow as shown in (Figure 1) is 29 kg. Assume the forearm and hand have a total mass of 2.0 kg with a CG that is 15 cm from the elbow, and that the biceps muscle attaches 5.0 cm from the elbow.

 The maximum mass m that a person can hold in a hand when the arm is positioned with a 105° angle at the elbow as shown in (Figure 1) is 29 kg. Assume the forearm and hand have a total mass of 2.0 kg with a CG that is 15 cm from the elbow, and that the biceps muscle attaches 5.0 cm from the elbow. 

Part A 

What is the maximum force Fimax that the biceps muscle exerts on the forearm?
