11.
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

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
