A pressure cooker is a covered pot sealed everywhere except for a small circular opening at the top. A small weight placed over this opening determines the pressure at which steam is released from the pot. Suppose that the radius of the opening is 0.450 mm and the weight is 0.848 N. Find the maximum pressure inside the pot.

Respuesta :

Answer:

1.02 N/mm2

Explanation:

We can see that the pressure is applied on the small weight that covers the opening.

The area of the circular opening is π(0.512 mm)

= 0.824 mm2

Pressure = Pressure = Force / Area

=  (0.847 N) / (0.824 mm2)

= 1.02 N/mm2
The Answer is 1.02 N/mm2
