A steel bar of 5 mm is heated from 15Â° C to 40Â° C and it is free to expand. The bar Will induce
A body is subjected to a tensile stress of 1200 MPa on one plane and another tensile stress of 600 MPa on a plane at right angles to the former. It is also subjected to a shear stress of 400 MPa on the same planes. The maximum normal stress will be
Two shafts ‘A‘ and ‘B‘ transmit the same power. The speed of shaft ‘A‘ is 250 r.p.m. and that of shaft ‘B‘ is 300 r.p.m. The shaft ‘B‘ has the greater diameter.
The stress induced in a body, when suddenly loaded, is __________ the stress induced when the same load is applied gradually.
If the slenderness ratio for a column is 100, then it is said to be a __________ column.

In order to prevent crushing of masonry at the base of the dam, the maximum stress should be __________ the permissible stress of the soil. 
When a body is subjected to two equal and opposite pushes, as a result of which the body tends to reduce its length, the stress and strain induced is compressive.
The maximum diameter of the hole that can be punched from a plate of maximum shear stress 1/4^{th}Â of its maximum crushing stress of punch, is equal to (whereÂ tÂ = Thickness of the plate)
Two closely coiled helical springs ‘A‘ and ‘B‘ are equal in all respects but the number of turns of spring ‘A‘ is half that of spring ‘B‘ The ratio of deflections in spring ‘A‘ to spring ‘B‘ is
