Question

An elastic material with modulus of elasticity E, and Poisson’s ratio  originally fills a square cavity of sides 2a and height h in a rigid block. A rigid cap is placed on top of the elastic material, and when there is a force acting on the cap, the height of the elastic material is observed to have decreased by an amount c.
Calculate the magnitude of the force F0

Answer 1

Answer:

hope its helpful

Explanation:

1. An elastic material with modulus of elasticity E and Poisson’s ratio ν originally fills a

square cavity of sides 2a and height L in a rigid block. A rigid cap is placed on top of

the elastic material, and when there is a force Fo acting on the cap the height of the

elastic material is observed to have decreased by an amount c. Calculate the

magnitude of the force Fo.
