Question

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

Answer 1

Hello,
----------

Here, Force = 600 N

Radius of surface = 1.4 m

Area = π × (1,4)² m²

= 22/7 × 1.4 × 1.4. m²

= 6.16 m²

We know,

Pressure = Force/Area

So, maximum pressure that the surface can withstand = 600/6.16 = 97.40 Pascal
