The lecture Pascal's Law by Jared Rovny is from the course Fluids.
You have a machine which applies 1000 Newtons of force to oil in a tube of crosssectional area 0.5 cm^2. If this oil goes to a piston with a movable wall of area 1 m^2, how much force can the piston apply?
Which of these is an accurate description of Pascal’s Law?
A barber raises his customer’s chair by applying a force of 150N to a hydraulic piston of area 0.01 m2. If the chair is attached to a piston of area 0.1 m2, how massive a customer can the chair raise? Assume the chair itself has a mass of 5 kg. What is the force applied to the larger piston, and the maximum mass that can be lifted? Use Pascal’s Law.
A hydraulic system is used to lift a 3000kg vehicle in an auto garage. If the vehicle sits on a piston of area 0.8 square meter, and a force is applied to a piston of area 0.05 square meters, what is the minimum force that must be applied to lift the vehicle?
