Following Civil Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :

16.If a composite bar of steel and copper is heated, then the copper bar will be under

tension

compression

shear

torsion

17.The relationship between Young's, modulus of elasticity E, bulk modulus K and Poisson's ratio u is given by

E = 2K(l-2u.)

E = 3K(l + u)

E = 3K(l-2u)

E = 2K(l + u)

18.Effective throat thickness of a fillet weld is

0.707 x size of weld

1.414 x size of weld

a function of the angle between fusion faces

equal to the side of the fillet

19.Size of fillet weld with unequal legs is equal to

smaller leg length

longer leg length

throat thickness

average of smaller and longer leg lengths

decrease

remain unchanged

increase to two times

increase to four times
