When you take your car into the shop to have it worked on, a hydraulic lift is used. The diameter of the piston lifting your car is 2.5m, while the input piston has a diameter of only .1m. your car and the base it sits on have a combined mass of 1200kg. The oil used in this lift has a density of 800kg/m^3.How many apples would you need to place on the input piston in order to hold up your car? A medium apple weighs approximately one newton.When the car reaches a height of .15m, how many apples will it take to support the car?
For the best answers, search on this site shorturl.im/avmN8 (a) Area of small piston: pi x radius x radius 3.142 x 2.04 x 2.04 13.1 cm^2 W 11.5 kN 11500 N Area of large piston pi x radius x radius 3.142 x 9.8 x 9.8 301.8 cm^2 Pressure needed at large piston Force / Area 11500 / 301.8 38.1 Pa Therefore force needed at small piston Pressure x Area 38.1 x 13.1 498.3 N (b) Hmmmmm this one got me thinking.and I frankly have not even a tiny clue. Sorry!!! (c) M.A. W / Fa 11500 / 498.3 2.31

Hydraulics work with the conservation of pressure. Since pressure is force / unit area, if you generation a pressure on one end, you can generate a large force on the other end by increasing the area. To balance: P1 P2 or Force1/Area1 Force2/Area2 On the car end, force: 1200 kg x 9.8 m/s^2 11760 N Area: pi x r^2 or pi x (d/2)^2 To find the pressure in the piston: 11760 / (3.14159 x (2.5/2)^2) 2395.728 N / m^2 You need the same pressure at the other end. Area of the input piston: 3.14159 x (0.1/2)^2 0.007854 m^2 P1 Force 2 / Area2 or Force 2 P1 x Area 2 Force needed: 2395.728 N / m^2 x 0.007854 m^2 18.816 N Since an apple weighs 1 N, you need 18.8 apples. For the second part, factor in the additional forces on the output piston due to the weight of the oil (800 kg/m^3) * 0.15 m, and perform the same math.
i wouldn't buy anything TRD but man why do you want to fix up a scion lol you are gonna be like one of those guys that pulls up next to me and revs and then when i take off it looks like you didn't even take your foot off the brake yet lol but i guess if i had to recommend something, i'd say go to you local exhaust place and have them custom make you something that's what i did on both my cars and now i have the perfect sound that i always wanted
