Question

1. Determine the pressure if the force acting on a circular object is 15 lbs and
its diameter is 5 cm.

​

Answer 1

Answer:

Step-by-step explanation:

force per unit area is called pressure.

radius=5/2 cm

area=π(5/2)²=25/4π

force=15 lbs

pressure=15÷25/4π=(15×4π)÷25=12π/5=2.4π lbs per square cm
