(Use the following values: L = 14 cm, d = 2 cm, M = 3 kg, and m = 2 kg.)

How large is the force exerted by the bicep?

I'm thinking that the torque of the forearm + the torque of the baseball combined are going to equal the negative of the torque provided by the bicep. Is this the right way to do this? And if so, I know how to figure out the torque from the baseball because I know it's distance. But how about the torque of the forearm? What is its distance? Can I just use average distance by dividing it by 2?

Thank you.
