Pick up the correct assumption of the theory of simple bending
The value of the Young's modulus is the same in tension as well as in compression
Transverse section of a beam remains plane before and after bending
The material of the beam is homogeneous and isotropic
The resultant pull or thrust on transverse section of a beam is zero
All the above.
Explanation:
No answer description is available. Let's discuss.

The neutral axis of a beam cross-section must
pass through the centroid of the section
be equidistant from the top of bottom films
be an axis of symmetry of the section
none of these.

If the beam is supported so that there are only three unknown reactive elements at the supports. These can be determined by using the following fundamental equation of statics
H = 0
V = 0
H = 0; ∑H = 0
H = 0; ∑V = 0; ∑M = 0
M = 0; ∑H = 0

In a solid arch, shear force acts
vertically upwards
along the axis of the arch
perpendicular to the axis of arch
tangentially to the arch
none of these.
