Question #128653

How much force must be applied on a blade of length 4cm and thickness of 0.1mm to exert a pressure of 4000000pa?

Expert's answer

The pressure by definition

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

Hence, the force applied on a blade

"F=PA\\\\\n=(4000000\\:\\rm Pa)\\times(0.04\\: m\\times 0.0001\\: m)=16\\: N"
