Question

A force of 26.4lb is applied to an area of 1.71 in2. What is the pressure?

A) 15.4 lb/in2
B) 0.0648 lb/in2
C) 45.1 lb/in2
D) 22.8 lb/in2

Answer 1

Pressure, P = 15.4 lb/in²

Step-by-step explanation:

Given that,

Force applied, F = 26.4 lb

Area of cross section, A = 1.71 in²

To find,

Pressure.

Solution,

Pressure is equal to force per unit area of cross section.

`P=(F)/(A)\\\\P=(26.4\ lb)/(1.71\ in^2)\\\\P=15.43\ lb/in^2\\\\P=15.43\ Pa`

Hence, the correct option is (a) "15.4 lb/in²".
