Answer:
<u> </u><u>The magnitude of the force exerted by the biceps </u>
<u> is 218.38N</u>
<u>The magnitude of the force exerted by the elbow </u>
<u> is 194.37N</u>
Explanation:
Firstly , lets calculate the magnitude of force exerted by biceps
-
Mass of the forearm=

Mass of the ball =

= 0.950kg
so, weight of the forearm=
g
weight of the ball=
g
Now , balancing torque about the elbow , we have-

(here , distance of the bicep is 2.50cm = 0.025m and distance of the ball is 36cm= 0.36m)
Now putting the given values in the formula -


Now, lets calculate the force exerted by elbow
-
Balancing the vertical forces
