A hand weight is equal to the 35N and forearm is held at a 45° angle to the vertically oriented humerus. The CG of the forearm and hand is located at a distance of 15 cm from the joint center at the elbow, and the elbow flexor muscles attach at an average distance of 3 cm from the joint center. (Assume that the muscles attach at an angle of 45° to the bones.). Identify the following: I. How much force must be exerted by the forearm flexors to maintain this position?
How much force must the forearm flexors exert if a 50 N weight is held in the hand at adistance along the arm of 25 cm?

no he didnt use it

explanation:

he said no

i don't understand really? can u provide more information

u should make a machine that can make ice cream fresh!
