To draw the Shear Diagram:
- VAB = -wox for segment AB is linear; at x = 0, VAB = 0; at x = L/2, VAB = -½woL.
- At BC, the shear is uniformly distributed by -½woL.
To draw the Moment Diagram:
- MAB = -½wox2 is a second degree curve; at x = 0, MAB = 0; at x = L/2, MAB = -1/8 woL2.
- MBC = -½woLx + 1/8 woL2 is a second degree; at x = L/2, MBC = -1/8 woL2; at x = L, MBC = -3/8 woL2.
