Check explanation.

Explanation:

From the question, we know that The person exerted 190N, force on the flexor is unknown. Since, we don't have access to our diagram, we have to make one or two assumption; (1) that ba = 0.3 m, ac = 0.05.

Therefore, the horizontal force that his flexor muscle exerts on his forearm, F (flexor) = (190N) * (0.3m) / 0.05m.

The horizontal force that his flexor muscle exerts on his forearm, F (flexor) = 57 Nm / 0.05 m.

The horizontal force that his flexor muscle exerts on his forearm, F (flexor) = 1140N.
