For the overhanging beam shown in figure, the magnitude of maximum bending moment (in kNm) is _______.

1. 3kNm
2. 4kNm
3. 5kNm
4. 5.5kNm

Correct Option: C

R_A + R_B = 60
R_B (4) = 20 (6) +10(4)(2)
R_B = 50CN
R_A = 10 KN
SF = R_A – 10x
SF_x=0 = 10KN
SF_x=4= –30KN
Bending moment is maximum where shear force is zero
∴ SF = R_A 10x = 0
R_A = 10x

BM_x-x = R_Ax -	10x²
	2

BM_x=1 = 10(1) -	10(1)²	= 5kNm
	2
