Given : On a piston of 10 cm diameter a force of 1000 N is uniformly applied
To find : the pressure on the piston
Solution:
Pressure = Force / Area
Force = 1000 N
Diameter = 10 cm
Radius = 5 cm = 5/100 = 1/20 m
Area = πr² = 3.14 * ( 1/20)² = 7.855/1000 m²
Pressure = Force / Area
= 1000 / (7.855/1000)
= 1000/ 7.855 KN/m²
= 127.307 KN/m²
the pressure on the piston = 127.307 KN/m²
