Question

What is the pressure of a 300 lb. object on a 100 sq. in. area?

O
30,000 psi
O
3,000 psi
O 300 psi
O 3 psi

Answer 1

D. 3 psi

Step-by-step explanation:

Pressure is defined as force acting per unit area and is numerically expressed as:

`P= \frac {F}{A}`

where P represent pressure, F is force and A is area where the force acts. Substituting 300 lb for force and 100 sq.in for area then pressure,

`P=\frac {300 lb}{100 in^(2)}= 3 \ psi`

Therefore, from the choices given, option D, 3psi is the right choice.
