Strength of materials top 10 mcq

01.Modular ratio of the two materials is the ratio of

their modulus of elasticities.

02.The Poisson's ratio for steel varies from

0.23 to 0.27.

03.When a rectangular beam is loaded transversely, the maximum tensile stress is developed on the

top layer.

04.Auto frettage is the method of

prestressing thick cylinders.

05.In a thick cylinder pressurized from inside, the hoop stress is maximum at

The inner radius.

06.The commonly used technique of strengthening thin pressure vessels is



Wire winding.

07.The distance between the center of a rivet hole to the nearest edge of plate, is called

margin.

08.A section of beam is said to be in pure bending, if it is subjected to

constant bending moment and zero shear force.

09.The planes, which carry no shear stress, are known as 

principal planes.

10.Transverse fillet welds are designed for
