Question
A diagram of a hypothetical 40 cm long arm is shown in Figure 4.15.
For the purposes of answering this question assume that the arm itself is weightless. If the muscle attached to the arm can contract at a rate of 7.0 cm s−1 with a force of 15 000 N then:
(a) What is the maximum
(b) What is the maximum weight that can held in the hand if the muscle is attached 1 cm from the elbow?
(c) What is the maximum angular velocity of the arm if the muscle is attached 3 cm from the elbow? (
d) What is the maximum weight that can held in the hand if the muscle is attached 3 cm from the elbow
