A truck has tyres of area 3 m². It puts a pressure of 4000 N/m^2 on the road. What is the weight of the truck? (Hint: Weight =Force)
Explanation
- Pressure = Force / Area
- 4000 N/m2 = Force / 3 m2
- Force = Pressure x Area
- Force = 4000 N/m2 x 3 m2
- Force = 12000 N
Since weight is equal to force, the weight of the truck is 12000 N.
