@ 43.20 -- Curve plotting confusion can be avoided by looking at the value of slope of the Bending Moment at 'A' .. which must be zero as the shear force at A is zero that means at a our tangent should be horizontal... that is only possible if we plot BMD curve inwards rather than outside... otherwise we will not get slope of BMD at A = zero......

Excellent lecture series!

7:11 problem 1 38:12 problem 2 40:10 general loading curve given then how to do the question 45:00 problem 3

In what way can we shift the moment from one position to another ? Like we used to resolve a force into a force and a moment.

🙏🏽

Sir ,I have taken upward direction as postive & I got different answers in what I am entirely different from ur SFD diagram sir.☹️

👍🏻

Sir can we use the second derivative test to determine the concavity of the curve to verify the SFD and BMD
