The Main shaft of a wind turbine is being redesigned As part

The Main shaft of a wind turbine is being redesigned. As part of the efforts, designers realized that it is necessary to calculate the deformations of the shaft that are produced by its own weight and by the weight of the flange-hub-blades assembly W. Complete the load, shear, and moment functions, using singularity functions, for the simply supported shaft. Then determine the critical points, sections, and principle stresses.

I currently have:

q(x) = -W<x-0>^-1 + R1<x-a>^-1 - W1<x-a>^0 + W1<x-b>^0 - W2<x-L>^0 + R2<x-L>^-1

Solution

I will try to help you.

1. draw free body diagram and mmention all the forces and moments (extrernal,self weight), support (reactions) in the system.

1.a find out reactions and reaction moments.

2. derive Force/moment equation using singularity. YOU RAE NOW HERE.

3. Integrate slope and deflection Functions from moment and load functions.\\

4. Boundary condition for solving functioins.

5. Draw shear and bending moment diagram!

coimg to your solution, you did everything right. i suggest you start the defining functions from support.
