Question

How much force must be applied on a blade of length 4cm and thickness 0.1mm to exert a pressure of 5000000 pa

Answer 1

20N

Step-by-step explanation:

L1 = 4 cm = 0.04 m

L2 = 0.1 mm = 0.0001 m

Area = 0.04 × 0.0001 = 0.000004 m²

Pressure = 4000000 Pa

Force = 4000000 × 0.000004 = 16 N
