Prashant Kumar 7 years, 10 months ago

At the very center,t he gravitational force is zero because there is equal mass pulling on you from all sides and it all cancel. If you built a room there, you could float freely .

What is shear strain?

Posted by Diwakar Patel 7 years, 10 months ago

CBSE > Class 11 > Physics

1 answers

Falguni Patidar 7 years, 10 months ago

When some external force is applied parallel to the cross -section ofcylindrical body or any other body , a relative displacement (x)is seen b/w both the opposite phases of that body . So the ratio of the displacement (x) to the original length (l) is known as shear strain .
