Students have asked these similar questions

Suppose the biceps muscle was attached through tendons to the upper arm close to the elbow and the forearm near the wrist. What would be the advantages and disadvantages of this type of construction for the motion of the arm?

If you are holding a 25lb weight in your hand 30cm from your elbow joint and your biceps brachii is generating a 30lb upward force at its attachment 5cm from the axis at 30° of elbow flexion, what will happen to the weight?

If the elbow was flexed to 135°, would the internal force required by the biceps brachii be greater than or less than the force when the elbow was flexed to 90°? Why?
