Question
The variation of bending moment due to UDL is:
A.
Uniform in nature
B.
Linear in nature
C.
Parabolic in nature
D.
Hyperbolic in nature
Answer ( Option C)

Parabolic in nature

Solution

The variation of bending moment due to UDL is parabolic.

 NOTE :-  

The degree of variation of bending moment is one degree higher than the variation in shear force and two degree higher than the variation in loading.
Table : Variation of SFD & BMD for different degree of loading conditions 
• Point at which a concentrated force is acting, there will be a sudden change in SFD and slope of BMD.
• A point at which a couple is acting there will be a sudden change in BMD
