44) The elasticity of various materials is controlled by its

Answer is:

stress at elastic limit

45) The ratio of lateral strain to the linear strain within elastic limit is known as

Answer is:

Poisson's ratio

Explanation:

Poisson's ratio is defined as the ratio of Lateral strain and longitudinal strain.

The ratio of lateral strain to the linear strain within elastic limit is known as

46) The ratio of direct stress to volumetric strain in case of a body subjected to three mutually perpendicular stresses of equal intensity, is equal to

Answer is:

bulk modulus

Explanation:

When a body is subjected to three mutually perpendicular stresses, of equal intensity, the ratio of direct stress to the corresponding volumetric strain is known as bulk modulus. Bulk Modulus is usually denoted by K.

47) The stress at which extension of the material takes place more quickly as compared to the increase in load is called

Answer is:

yielding point of the material
