A solid shaft of 65mm outside diameter and a hollow shaft of 85mm outside diameter are connected by 6 bolts with the mean pitch of thread being 155mm. The shear stress due to the torque on the shafts is equal to the shear stress on the bolts.
a) Find the diameter of the bolts.

b) Find the inside diameter of the hollow shaft.

Solid shafts and larger diameter hollow shafts are usally connected throught a flange welded over the smaller diameter of the solid shaft. The flange outside diameter is the same as the hollow shaft. Bolts are then used to secure the two shafts together.
