Question

Calculate the diameter of pneumatic cylinder to drive a mechanism. The force exerted by the mechanism is 80 N. The return force is negligible. The working pressure is 5 bars.

Answer 1

14.27 mm

Step-by-step explanation:

Force = 80 Newton

Pressure exerted = 5 bar = 5×10⁵ Pa

Pressure exerted = Force/Area

Area = Force/Pressure

`Area=(80)/(500000)\\\Rightarrow Area=0.00016\ m^2`

Area of the cylinder=πd²/4

`\Rightarrow (\pi)/(4)d^2=0.00016\\\Rightarrow d^2=(4* 0.00016)/(\pi)\\\Rightarrow d^2=0.0002037\\\Rightarrow d=0.01427\ m`

Hence diameter of cylinder 14.27 mm
