Hi, in this question we have propped cantilever, so propped cantilever ab counterclockwise moment.
00:19
So here we have a counterclockwise moment is m0.
00:23
So here we have to find the slope of the b using superposition.
00:27
So we have slope of b using superposition, so using effect of applied moment at b, m0 at b and effect of beam's weight, then we have effect of, so effect of applied moment at b0 is given by, so m0 at b is given by, it is minus m0 divided by ei which is equal to theta of moment, where e is the modulus of the velocity, then addition of beam's weight is given by theta load is equal to w into x square divided by 2 into ei, where w is the weight per unit length of the beam and x is the distance at the free end.
01:33
Now we have slope at b is given by, so slope at b is given by adding these two, so 1 and 2, so 2, adding 1 plus 2, we have slope at b is equal to minus m0 divided by ei plus omega x square divided by 2 ei.

Then for the second case, we have confirming using first moment area method.
02:08
So here for this method, we need to find the area of the bending moment...
