Consider a thin-walled cylindrical vessel having diameter 'x' and wall thickness 't' subjected to an internal pressure 'I'. What would be the value of the maximum shear stress in the plane of the cylinder wall?

A 40 cm long and 10 cm diameter brass cylinder was subjected to a tensile load of 50,000 N. The resulting increase in length and decrease in diameter were noted to be 0.8 mm and 0.05 mm respectively. Find the Poisson's ratio of brass.

A shaft of 60 mm diameter subjected to torsion has a shear strain of 0.0006 at the outer surface. The rate of twist will be equal to:
