Electrical outlets are pressed from a special mass (barkalite), acting on it with a force of 37.5 kN.

Electrical outlets are pressed from a special mass (barkalite), acting on it with a force of 37.5 kN. The outlet area is 0.0075 square meters. Under what pressure are the sockets pressed?

Given:

F = 37.5 kN – the force with which they act on the socket;

s = 0.0075 square meters – outlet area.

It is required to determine P (Pascal) – the pressure with which the rosettes are pressed.

Let’s convert units of force measurement from kN to Newton:

F = 37.5 kN = 37.5 * 1000 = 37500 Newton.

Then we find the pressure from the following formula:

F = P * s, hence:

P = F / s = 37500 / 0.0075 = 5,000,000 Pascal = 5 MPa.

Answer: The rosettes are pressed under a pressure equal to 5,000,000 Pascal (5 MPa).
