Q. Write down the basic formula for maximum bending moment in some ideal cases.

Sol.:

	Berm together with nature of load	Maximum B.M.	Section when maximum B.M. occurs
1.	Cantilever loaded with 1 point load wat the free end.	WL	It occurs at fixed end.
2.	Cantilever loaded with U.D.L. over entire length.	WL2 2 here W = total value of U.D.L. 20 × l	It occurs at fixed end.   w/unit length

	Berm together with nature of load	Maximum B.M.	Section when maximum B.M. occurs
3.	Boam loaded with 1 point load at the mid-span.	WL 4 where W = point load placed at mid-span.	If occurs at mid-span.
4.		WL2 8 where W = total value of U.D.L. = 20 × l.	If occurs at mid-span. w/unit length     l
