Question

The beam shown in the given figure has a design bending moment value of

• A. 8 kN -m
• B. 6 kN - m
• C. 4 k N-m
• D. 2kN-m

Answer 1

The correct option is D 2kN-m

(d)
4kN- m moment is sagging
2kN- m moment is hogging
BMDs
(i) Due to 4kN load
(ii) Due to 4kN-m moment
(iii) Due to 2 kN-m moment
BM at A = 0
BM at B = 4 - 2 = 2 kN-m sagging
BM at C = - 2 kN- m hogging
So design BM is 2 kN-m
