[#81] A beam extending beyond the supports is called
Correct Answer

(C) Overhanging beam

[#82] When a rectangular bar of length $$l$$, breadth b and thickness t is subjected to an axial pull of P, then linear strain ($$varepsilon $$) is given by (where E = Modulus of elasticity)
Correct Answer

(A) $$varepsilon = frac{{ ext{P}}}{{{ ext{btE}}}}$$

[#83] The shape of cantilever for uniformly distributed load will be
Correct Answer

(B) Parabolic

Explanation

Solution: When a uniformly distributed load is applied to a cantilever beam, the shape of the deflected beam will form a parabolic curve . This is a common phenomenon observed in cantilever beams under such loading conditions. Therefore, the correct answer is Option B: Parabolic , as the shape of a cantilever under a uniformly distributed load is parabolic in nature. This is a fundamental concept in the field of strength of materials in mechanical engineering.
