78) The point of contra flexure occurs in

cantilever beams

simply supported beams

overhanging beam

fixed beams

Answer is:

overhanging beam

Explanation:

The point where the bending moment changes sign is known as point of contraflexure. Point of contraflexure generally occurs in overhanging beams.

79) The bending moment at a section tends to bend or deflect the beam and the internal stresses resist its bending. The resistance offered by the internal stresses, to the bending, is called

compressive stress

shear stress

bending stress

elastic modulus

Answer is:

bending stress

80) The assumption, generally, made in the theory of simple bending is that

the beam material is perfectly homogenous and isotropic

the beam material is stressed within its elastic limit

the plane sections before bending remain plane after bending

all of the above

Answer is:

all of the above

81) In a simple bending theory, one of the assumption is that the material of the beam is isotropic. This assumption means that the

normal stress remains constant in all directions

normal stress varies linearly in the material

elastic constants are same in all the directions

elastic constants varies linearly in the material

Answer is:

elastic constants are same in all the directions
