Question 3

Consider the following joints:
1). railways carriage wheel and axle
2). IC engine cylinder and line
Which of the above joints is/are the result(s) of interference fit?

Question 4

Maximum shear stress developed on the surface of a solid circular shaft under pure torsion is 240 MPa. If the shaft diameter is doubled, then what is the maximum shear stress developed corresponding to the same torque?

Question 5

A circular shaft which has a diameter of 100 mm is subjected to a torque of 5 kN-m. The shear stress, in N/mm2, induced in the shaft would be

Question 6

The ratio of torsional moments of resistance of a solid circular shaft of diameter D to that of a hollow shaft with external diameter D and internal diameter d is

Question 7

Assertion (A): Shearing force may be defined as the rate of change of loading moment.
Reason (R): Shearing force at a section is the algebraic sum of the forces to the left of the section.

Question 8

Statement (I) : The most-suited failure theory for concrete is maximum shear strength theory.
Statement (II) : Ductile materials are limited by their shear strength.

Question 9

Which of the following stresses is measured on surface in Mohr's Circle Method?

A. Principal stress
B. Tangential stress
C. Maximum stress
D. Normal stress

Question 10

The base of a column is subjected to moment .If the intensity of bearing pressure due to axial load is equal to stress due to moment, then the bearingpressure between the base and the concrete is
