Question

A perpendicular force of 600 N acts on a circular surface of radius 1.4m. The surface will break if the additional perpendicular force of 16 N is applied on it. the maximum that the surface can withstand is

Answer 1

Surface area= πr square= 22/7×1.4×1.4=22/10×2×1.4=(22×2.8)/10=61.6/10=6.16m square. Pressure=Thrust/area = 600/6.16=97.40pa approx. additional pressure=616/6.16=100 pa Thus the object can withstand only the pressure maximum up to 99.9pa.
