In the hollow multi-cell cross-section the dimensions and

the shear flow directions within each cell are shown in

the figure. If the shear modulus of the aluminum is G =

26.0GPa and the applied torque is T =1.5kN-m.

2-3 mm Calculate:

a) shear flows: q1, q2, q3,

b) shear stresses: T1, T2, T3,

c) angle of twist per unit length,

d) torsional rigidity per unit of rotation.
