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

82) In a simple bending of beams, the stress in the beam varies

linearly

parabolically

hyperbolically

elliptically

Answer is:

linearly

83) 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
