1. Pressing force = 10N , Area= 2m2 : Calculate pressure in N/m2
2. Pressing force = 70N, Area = 0.2m2 : Calculate pressure in N/m²
3. Pressing force = 300N , Area = 0.01m?: Calculate pressure N/m
4. Pressing force = 500N, Pressure = 20N/m² : Calculate area in m
5. Area = 0.003m2, Pressure = 15000N/m2 : Calculate the pressing force in N
I am so confused

1 Pressing force 10N Area 2m2 Calculate pressure in Nm2 2 Pressing force 70N Area 02m2 Calculate pressure in Nm 3 Pressing force 300N Area 001m Calculate pressu class=

Respuesta :

You need the triangle to help work it out.
Force (pressing force) = Pressure x Area.
1. Force/ Area - 10/2 = 5N/m2
2. (Same as Q1) 70/0.2 = 350N/m2
3. (Same as Q1) 300/0.01 = 30000N/m2
4. Force/pressure - 500/20 = 25m
5. Pressure x Area - 15000 x 0.003 = 4.5N
