31. The ratio of change in volume to the original volume is called. [RRB S.S.E (Bhopal) 21.12.2014 ]

Correct Answer: (c) Volumetric strain
Solution:The ratio of change in volume to the original volume is called volumetric strain.

32. Brass is an alloy of [RRB JE (Bilaspur/Guwahati/Patna) 14.12.2014 ]

Correct Answer: (a) copper and zinc
Solution:

Brass is an alloy of copper and zinc.
• The properties of zinc and copper can be varried to create a range of brasses with varying properties.
• It is used for decoration for its bright gold-like appearance.

33. A simply supported beam of span L and flexural rigidity El, carries a unit point load at its centre. The strain energy in the beam due to bending is [RRB JE (Bilaspur/Guwahati ) 14.12.2014 ]

Correct Answer: (c)
Solution:

34. The stress–strain curve for an ideally plastic material is [RRB JE (Bilaspur/Guwahati ) 14.12.2014 ]

Correct Answer: (c)
Solution:

Stress-Strain Curve for Different Types of Material-

35. In terms of bulk modulus (K) and modulus of rigidity (G), Poisson's ratio can be expressed as [RRB JE (Bilaspur/Guwahati ) 14.12.2014 ]

Correct Answer: (c)
Solution:

36. In a situation where torsion is dominant, which one of the following is the desirable section? [RRB JE (Bilaspur/Guwahati ) 14.12.2014 ]

Correct Answer: (d) Box–Type Section
Solution:

For torsion resistance the best section is solid circular shaft or hollow circular shaft. These section should be away from the axis of the section and it should symmetrical about the axis. These box section is most desirable.

37. Which of the following processes is the wire drawing process? [RRB JE (Bilaspur/Guwahati ) 14.12.2014 ]

Correct Answer: (b) Tensile
Solution:

Wire drawing is a cold working process to obtain wires from rods of bigger diameters through a die, the wire is subjected to tensile only.

38. A simply supported beam carries a varying load from zero at one end to w N/m at the other end (as under) [APPSC AE PRE.-15.05.2022 / RRB S.S.E (Bilaspur/Secunderabad) 21.12.2014 ]


The length of the beam is L. The shear force will be zero at a distance 'x' from A. Find 'x':

Correct Answer: (c) L/√3
Solution:


39. In a three–hinged arch, the Bending Moment will be zero at: [RRB S.S.E (Bilaspur/Secunderabad) 21.12.2014 / (RRB Bilaspur JE, 21.12.2014)]

Correct Answer: (d) All the three Hinges
Solution:

40. The property of a material by which it can be rolled into sheets is called: [RRB JE (Bilaspur/Kolkata/Mumbai/ Guwahati)-14.12.2014 / BPSC AE (GEN ENGG.)-03.12.2012]

Correct Answer: (d) Malleability
Solution:

Malleability–It is the ability to be compressed. It is often characterized as the materials ability to form a thin sheet when rolled.

Ductility–It is the ability to be stretched. It is often characterized as the material ability to be pulled into a wire.
