Design a hydraulic system for lifting a 500 kg vehicle with a pneumatic setup using Pascal's Law. What size pistons would be required?
💡 Hint: Utilize the pressure formula, P = F/A, where the pressures in both pistons are equal.
A hydraulic press has a small piston with a diameter of 5 cm and a large piston with a diameter of 20 cm. If 100 N is applied to the small piston, find the force exerted by the large piston.
💡 Hint: Remember that area increases by the square of the radius when moving from small to large diameters.
