Question

You have a suction cup that creates a circular region of low pressure with a 30 mm diameter. It holds the pressure to 85 % of atmospheric pressure. What "holding force" does the suction cup generate in N

Answer 1

Answer:

Force = 60.08 N

Explanation:

Given that

Diameter d = 30 mm  

Holding pressure = 85 %  of Atmospherics pressure

Solution

As we know that  here 1 atm = 10⁵ N/m²

and pressure is known as force per unit area

pressure = $\frac{F}{A}$   ................1

put here value and we will get

F = $0.85\times 10^5\times \frac{\pi}{4}\times 0.03^2\ N$

solve it we get

Force = 60.08 N
