A wheel of diameter 2 m can be rotated about an axis passing through its centre by a moment of force equal to 2.0 N m. What minimum force must be applied on its rim?

A normal force of 200 N acts on an area 0.02 m². Find the pressure in pascal.

Find the area of a body which experiences a pressure of 50,000 Pa by a thrust of 100 N.

Calculate the pressure in pascal exerted by a force of 300 N acting normally on an area of 30 cm².
