A cylindrical shell made of mild steel plate of 100 cm diameter is to be subjected to an internal pressure of 10 kg/cm2. If the material yields at 2000 kg/cm2, assuming factor of safety as four and using maximum principal stress theory, thickness of the plate will be-A-5 mmB-10 mmC-15 mmD-20 mm-B-10 mm

Question

APTITUDE CRACK · Accepted Answer

B 10 mm According to max principal stress theory. Yield stress = applied stress * f.o.s. In above problem, applied stress is a hoop stress type and it is equal to (pd/2t). So, 2000=pd/2t * f.o.s. 2000=(10 * 100/2 * t) * 4. t = 1cm = 10mm.
