Which test is conducted to measure the endurance limit of the material? An axial pull of N on a bar consisting of two lengths as shown with their respective dimensions.

What will be the total elongation of the member, assuming the modulus of elasticity to be 2. The cross sectional area is mm, mm, mm respectively. A composite bar of two sections of equal length and given diameter is under an axial pull of 15kN. A round bar made of same material consists of 4 parts each of mm length having diameters of 40mm, 50mm, 60mm and 70mm, respectively.

If the bar is subjected to an axial load of 10kN, what will be the total elongation of the bar in mm? An axial pull of N is acting on a bar consisting of two lengths as shown with their respective dimensions. A composite bar consists of a bar enclosed inside a tune of another material when compressed under a load as whole through rigid collars at the end of the bar. Shear flow is defined as:. In a beam with symmetrical I cross section, the maximum shear stress is carried:. A beam of rectangular section of breadth 15 cm and 30 cm is subjected to a bending moment of 4 kN-m.

The stress developed at a distance of 15 cm from the top face is:. A simply supported beam of length 3 m is subjected to a uniformly distributed load of 1. Beams of uniform strength vary in section such that:. In the theory of bending, the assumption that the plane section before bending will remain plane after the bending is made to ensure that:.

It is subjected to a uniform B. What is the radius of curvature of the circle into which the beam will bend in the form of an area of a circle?

A rectangular metallic nail is inserted in a rubber sheet as shown in the figure. Answer: Option D Explanation: No answer description available for this question. For a beam, if fundamental equations of statics are not sufficient to determine all the reactive forces at the supports, the structure is said to be A.

Answer: Option C Explanation: No answer description available for this question. The moment diagram for a cantilever carrying linearly varying load from zero at its free end and to maximum at the fixed end will be a A.

The maximum deflection of A.
