118. Medical The bones of the forearm (radius and ulna) are hinged to the humerus at the elbow (Figure 8-65). The biceps muscle connects to the bones of the forearm about 2 cm beyond the joint. Assume the forearm has a mass of 2 kg and a length of 0.4 m. When the humerus and the biceps are nearly vertical and the forearm is horizontal, if a person wishes to hold an object of mass M so that her fore- arm remains motionless, what is the relationship between the force exerted by the biceps muscle and the mass of the object?

118... Medical The bones of the forearm (radius and
alna) are hinged to the humerus at the elbow (Figure 8-65).
The biceps muscle connects to the bones of the forearm
about 2 cm beyond the joint. Assume the forearm has a mass
of 2 kg and a length of 0.4 m. When the humerus and the
biceps are nearly vertical and the forearm is horizontal, if a
person wishes to hold an object of mass M so that her fore-
arm remains motionless, what is the relationship between
the force exerted by the biceps muscle and the mass of the
object? Example 8-17
