Exercise 5.10
The segment forearm-hand weighing 15 N with an additional
weight of 50 N on the hand, at 25 cm from the elbow, is maintained at 45
with
the humerus oriented vertically, as shown in the figure of Exercise 5.10. The center
of gravity of the forearm-hand is located at 15 cm from the articular center of
the elbow, and the flexor muscle is inserted at 3 cm from the articular center.
Determine the intensity of the flexor muscle force to maintain this position and
classify the type of lever. (sin 45
