g You have a suction cup that creates a circular region of low pressure with a 30 mm diameter. It holds the pressure to 78 % of atmospheric pressure. What "holding force" does the suction cup generate in N

Respuesta :

Answer:

F=49.48 N

Explanation:

Given that

Diameter , d= 30 mm

Holding pressure = 70 % P

P=Atmospherics pressure

We know that

P= 1 atm = 10⁵ N/m²

The force per unit area is known as pressure.

[tex]P=\dfrac{F}{A}[/tex]

[tex]F=P\times A[/tex]

[tex]F=0.7\times 10^5\times \dfrac{\pi}{4}\times 0.03^2\ N[/tex]

Therefore the force will be 49.48 N.

F=49.48 N
