An aluminum cylinder with a radius of 2.5 cmcm and a height of 82 cmcm is used as one leg of a workbench. The workbench pushes down on the cylinder with a force of 3.2×104N3.2×104N. What is the compressive strain of the cylinder? Young's modulus for aluminum is 7.0×1010Pa7.0×1010Pa. Express your answer using two significant figures.

To solve the problem, it will be necessary to apply the concepts related to Young's Modulus, which defines the relationship between stress and strain in a body. This mathematical relationship is explained below

But here,

Where,

A = Area

F = Force

r = Radius

In the formula of Young modulus we have then,

Replacing,

Therefore the strain is

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
