Q1. A wooden plank exerts a thrust of 200 N on a surface of area 4 m^2. What pressure does it produce?
- A.800 Pa
- B.204 Pa
- C.50 Pa
- D.0.02 Pa
Answer: C. 50 Pa
Pressure P = thrust / area = F/A = 200 N / 4 m^2 = 50 Pa.
Q2. If A metal sheet presses on the ground with a force of 600 N spread over 3 m^2, how great is the pressure?
- A.603 Pa
- B.1800 Pa
- C.0.005 Pa
- D.200 Pa
Answer: D. 200 Pa
Pressure P = thrust / area = F/A = 600 N / 3 m^2 = 200 Pa.
Q3. A glass tabletop pushes down with 150 N over a contact patch of 5 m^2. Calculate the pressure on the floor?
- A.0.03333 Pa
- B.155 Pa
- C.750 Pa
- D.30 Pa
Answer: D. 30 Pa
Pressure P = thrust / area = F/A = 150 N / 5 m^2 = 30 Pa.
