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

Answer:

14.27 mm

Explanation:

Force = 80 Newton

Pressure exerted = 5 bar = 5×10⁵ Pa

Pressure exerted = Force/Area

Area = Force/Pressure

$Area=\frac{80}{500000}\\\Rightarrow Area=0.00016\ m^2$

Area of the cylinder=πd²/4

$\Rightarrow \frac{\pi}{4}d^2=0.00016\\\Rightarrow d^2=\frac{4\times 0.00016}{\pi}\\\Rightarrow d^2=0.0002037\\\Rightarrow d=0.01427\ m$

Hence diameter of cylinder 14.27 mm
