Following Mechanical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :

16.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

Young's modulus
bulk modulus
modulus of rigidity
modulus of elasticity
Poisson's ratio.

17.For which material the Poisson's ratio is more than unity

steel
copper
aluminum
cast iron

18.The stress necessary to initiate yielding is

considerably greater than that necessary to continue it
considerably lesser than that necessary to continue it
greater than that necessary to stop it
lesser than that necessary to stop it
equal to that necessary to stop it.

19.In question 56, the internal reaction in bottom 80 cm length will be

same in both cases
zero in first case
different in both cases
data are not sufficient to determine same
none of the above.

20.The stress at which extension of the material takes place more quickly as com�pared to the increase in load is called

elastic point of the material
plastic point of the material
breaking point of the material
yielding point of the material
ultimate point of the material.
