When you step on the brakes, you are compressing a narrow piston (radius 2 cm), creating pressure in a closed system. Mechanical advantage is gained by having the fluid in-turn compress a larger piston (radius 10 cm). If you apply a force of 20 N to the small piston, what is the force delivered to the large piston? If the small piston compresses by a distance of 5 cm, how much does the large cylinder move by?

An explosion inside a factory produces a pressure wave of 2lb/in2 against a window. Find the force exerted on the window if it measures 3 meters by 2 meters.

If F1 = 390 N force is applied to the piston with d1 = 4 cm diameter, what is the magnitude of the force F2 that can be resisted by the piston with d2 =  10 cm diameter? Neglect the weights of the pistons.

Determine the tension, T, in Newtons, in the string, where v= 7 m/s, r= 74 cm, m = 8 kg and | m = 33⁰

An aquarium 7ft long, 3ft wide, and 5ft deep is full of water. The gravitational acceleration is g = 32ft/s². The density of water is p = 1.95slug/ft³. Answer the following questions. 1.

How can the equivalent point forces of fluids be found?

The round holes drilled in the sides and decks to illuminate the interior of the ships are called "portholes". If the center of a 30 cm diameter porthole of a ship is 10 m below the water level, how many N is the hydrostatic force acting on this porthole? Take the density of the water as 1000 kg / m3, the gravitational acceleration as 10 m / s2 and the value as 3.
