An elephant’s legs have a reasonably uniform cross section from top to bottom, and they are quite long, pivoting high on the animal’s body. When an elephant moves at a walk, it uses very little energy to bring its legsforward, simply allowing them to swing like pendulums. For fluid walking motion, this time should be half the time for a complete stride; as soon as the right leg finishes swinging forward, the elephant plants the right foot and begins swinging the left leg forward.a. An elephant has legs that stretch 2.3 m from its shoulders to the ground. How much time is required for one leg to swing forward after completing a stride?b. What would you predict for this elephant’s stride frequency? That is, how many steps per minute will the elephant take?

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.
