A solid cube is subjected to equal normal forces on all its faces. Volumetric strain will be how many times of the linear strain.

A solid cube is subjected to equal normal forces on all its faces. Volumetric strain will be how many times of the linear strain. Correct Answer 3

Explanation:

Volumetric strain:

It is defined as the ratio of change in volume to the initial volume of the body. It is equal to the sum of strain in all directions.

Equal normal forces are acting on all faces of the cube, so strain will be equal in all directions(ϵx = ϵy = ϵz).

ϵv = ϵx + ϵy + ϵz    

ϵv = 3ϵx   

Hence, Volumetric strain is 3 times the strain in all direction.

A cube of volume 64 cm3 is is cut into two smaller and identical cuboids. The faces of dimensions 4 × 4 of one of the cuboids are painted with black color and the rest of its faces are painted with yellow color. One pair of adjacent faces that do not include any face of dimensions 4 × 4 of the other cuboid are painted with yellow color and the rest of its faces are painted with black color. Now each of two cuboids are cut into 32 smaller and identical cubes. How many of the smaller cubes have exactly three colored faces?
