Question:

Physics: Find ratio of large force to the small force?

In a hydraulic lift the radii of the pistons are 1.75 cm and 14.0 cm. An SUV of mass 1850 kg is to be ifted by the force of the large piston. (a) Find the mechanical advantage of the lift (ratio of the large force to the small force).(b) What force must be applied to the small piston to lift the SUV? (c) When the small piston is pushed 10.0 m, how far is the car lifted?Thank you!

Answer:

Start out with a mid size bikesomething like a Harley sportster or a Honda shadow 600. If you go with a small bike like a 250. you'll out grow that bike the first year. THEN take a riding course.and, if you lay a bike down (which is not uncommon, just getting started) it's not YOUR bike that gets the dents the courses are worth every penny at that, if you want more practice, then go to a large empty parking lot. but, honestly consider a mid sze bike. I have a friend that bought a smll bike, and by the middle of that summer, was kick herslf. but had to wait until the end of the following summer (cause she spent her money on the smaller bike) before she could up grade
250 honda rebel. 500$ 883 sporster 6to 7 000$ not to ohard to figure that one out. also i suggest an endouro! looks like a motocross bike drives like a motocrossbike has a less agressive tire and has signals for street legal. they r a riot. used maybe a good one for a grand. this way you get to learn on and off highway riding at the same time. watch out for old dudes in cadillac's they will kill you.
Start out with a smaller bike like a 250 cc engine. Call some motorcycle dealers and ask them if they are aware of anybody that teaches a motorcycle safety class
(a) Find the mechanical advantage of the lift (ratio of the large force to the small force). Depends on the cross-sectional area of the pistons: MA 14^2 / 1.75^2 The rest is simply math (b) What force must be applied to the small piston to lift the SUV? 1850 kg ^ 9.8m/s^2 / MA from above (c) When the small piston is pushed 10.0 m, how far is the car lifted? 10.0 m / MA from above
