Question

How much force must be applied on a blade of length 4 centimetres and the thickness of 0.1 centimetres exert pressure of 5000000 pascal

Answer 1

Hi,

Here is your answer

Given:

Length=4cm=0.04m

Thickness=0.1cm=0.001m

Pressure=5000000Pa

To Find:

Force

Solution:

Area of the blade=length×thickness=0.04×0.001=0.00004 m²

Pressure=Force/Area

Hence

Force=Pressure×Area

Force=5000000×0.00004

Force=200N

Notes:

1. Remember to convert all the given datas to the SI units before calculating.

2. The unit of force in SI system is Newton and in CGS system is dyne.

Hope this helps you.
