What is the magnitude of the force exerted by the biceps fbiceps? What is the magnitude of the force exerted by the elbow felbow?

The magnitude of the force exerted by the biceps is 218.38N

The magnitude of the force exerted by the elbow is 194.37N

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
