Questions on PressureQ10. A large crate of dimensions: 2m long, 1.5m deep and 1m high has a mass of 300 kg.
What pressure does it exert on the ground if it is placed on its largest side? (Take the gravitational field strength as 10 N/kg) Area of largest side = 2m x 1.5m = 3m2 w = mg Weight of crate = 300 x 10 = 3000 N Pressure = F/A = 3,000/3 = 1,000 N/m2 Maximum 4 marks |
