The figure shows a cantilever beam of length with torsion stiffness GK and a torsion moment M¯ applied at x = .
a) Integrate the stiffness relation
Mx(x) to obtain an expression for ?(x).
b) Determine the arbitrary integration constant in a) via the boundary condition in x = 0.
c) Find the expression for the angle of twist ?() at the tip of the beam.
