Question

Problem 6

Answer 1

Given information

Mammalian lower legs are slender, with flesh and muscle concentrated high and close to the body in mammals that depend on their ability to run quickly.

Step-by-step explanation

Step 1.

There is a rotation of the leg about the point at which it is attached with the body.

Therefore, the faster of running causes the change in the leg's rotation.

The resistance to change in the rotational motion is directly proportional to the moment of inertia. Smaller be the moment of inertia smaller will be the resistance.
