Q.  What is the shape of BMD for this diagram?

Solution:

Answer: b
Explanation: It will be 0 till point B, and then will increase till C and then again decrease till D (every time linearly), thus making it triangular

QUESTION: 4

Q.  What will be the peak value of SFD?
Solution:

Answer: c
Explanation: It will decrease to 20 at point B and then increase by 80 at point C and then will remain constant. So, peak value will be 80-20 i.e. 60KN.

Q.  Where would peak value of BMD lie?
Solution:

Answer: c
Explanation: It will be 0 till point B, and then will increase till C and then again decrease till D (every time linearly), thus making it triangular.
