Question 1

A steel rod 10 m long is a temperature of 20 °C. The rod is heated to a temperature of 60 °C. What is the stress induced in the rod if it is allowed to expand by 4 mm, when E = 200
GPa and

= 12 × 10^–6/ °C?

Question 2

Universal Testing Machine can be used to perform tests on:

Question 3

A steel rod of length L and diameter D, fixed at both ends, is uniformly heated to a temperature rise of T. The Young’s modulus is E and the coefficient of linear expansion is α. The thermal stress in the rod is Δ

Question 4

In Ball Indentation Test shown, if L is constant load and area of spherical surface in indentation is A sq. mm, then Brinell Hardness Number is written as:

Question 5

A circular bar rigidly fixed at its both ends uniformly taper from 150 mm at one end to 100 mm at the other end. If its temperature is raised through 30K, what will be maximum stress developed in the bar.

Question 6

A short column of external diameter D and internal diameter d carries an external load W. The greatest eccentricity which the load can have without producing tension on the cross section of the column is

Question 7

If a material expands freely due to heating it will develop __________.

Question 8

A hypothetical engineering stress-strain curve shown in the figure has three straight lines PQ, QR, RS with coordinates P(0,0), Q(0.2,100), R(0.6,140) and S(0.8,130). 'Q' is the yield point, 'R' is the UTS point and 'S' the fracture point.
