Question

In an emergency situation,
a person with a broken forearm
ties a strap from his hand to clip
on his shoulder as in Figure P8.92.
His 1.60-kg forearm remains in a
horizontal position and the strap
makes an angle of θ = 50.0° with
the horizontal. Assume the forearm
is uniform, has a length of
l= 0.320 m, assume the biceps
muscle is relaxed, and ignore the
mass and length of the hand. Find
(a) the tension in the strap and
(b) the components of the reaction
force exerted by the humerus
on the forearm.
