Question

An object that crushes under its own weight would fracture _____.

near the bottom


at a completely random location


near the vertical midpoint


near the top

Increasing the Young’s modulus of a column will cause it to buckle more easily.

True

False


Increasing the area moment of inertia of a column will cause it to buckle more easily.

True

False

Answer 1

near the bottom

True

False

Step-by-step explanation:

If an object crushes due to its weight, it will fracture from bottom first. Young modulus increase will cause buckling easily due to stress. The soft material have nearly zero young modulus. The more the area under moment of inertia there will be less bending causing if difficult to buckle.
