The maximum mass m1

The maximum mass m1 that a person can hold in a hand when the arm is     positioned with a 1050 angle at the elbow as shown in is 18 kg. Assume the forearm and hand have a total mass of m2=2 kg with a center of   gravity   that is 15 cm from the elbow, and that the biceps muscle  attaches 5 cm from the elbow.

 

    a. What type of lever is illustrated in the figure?

    b. Consider the arm keeps a horizontal position and apply the     rotational equilibrium condition to determine the maximum force Fmax   that the biceps muscle exerts on the forearm?
