Pressure Flashcards
What is the formula for pressure?
Pressure = force/area
What are the units for pressure?
Pa or N/m2
How can a hydraulic system increase the force?
by having one cylinder biiger than the other
A force of 150 N is being applied over an area measuring 0.5 m. Calculate the pressure on the object ensuring you give the correct units.
300 N/m2
A woman is applying 300 N/m2 of pressure onto a door with her hand. Her hand has an area of 0.02 m2. Work out the force being applied
6 N
Pressure of 150 N/m2 is experience when a force of 2 kN is applied. Calculate the area over which the force is applied. Calculate the area over which the force is apllied to obtain the pressure stated.
13.3 m2
A force of 185.6 N is applied to a square of length 3m. Work out the pressure on the square to 3 significant figures.
20.6 N/m2
A man with a weight of 740 N is standing on one leg. HIs foot is exerting 2312.5 N/m2 of pressure onto the ground. What is the surface area of the bottom of his foot?
0.32 m2
A shipping container is removed from a ship and placed on the ground. The area of the container in contact with the ground is 16 m2. The pressure exerted on the floor is 2480 N/m.
What force is being exerted by the shipping container on the ground?
39,680 N
A cylinder is resting is resting on one of its circular faces on the ground. The weight of the cylinder is 4872 N and the cylinder exerts a pressure of 812 N/m2 on the ground.
To 2 decimal places what is the diameter of the cylinder?
2.76 m
A cube and a square-based pyramid exert the same pressure on the ground.
The square of the pyramid’s base has a side length of 8 meters and has a weight of 440N. The cube has weight of 110N. What is the side length of the cube?
I Dont know. The website didn’t tell me.
