Figure 4.18 A two-cell tube.
Fig. 4.18, the cell areas are: A1 =
40 cm2 , A2 = 60 cm2 . The wall
lengths are: L12 = 13 cm, L13 =
10 cm, L34 = 8 cm. The wall thick-
nesses are: t12 = t23 = 2 mm, t13 =
1 mm, t34 = t41 = 3 mm. If the
applied torque is 200 Nm and the
modulus of rigidity is 20 GPa, com-
pute the shear stresses in the walls and
the rate of twis
