Question:

In a hydraulic lift, the radii of the pistons are 2.11 cm and 10.5 cm. Physics help!?

A car weighing W 9.7 kN is to be lifted by the force of the large piston. (a) What force Fa must be applied to the small piston? Enter a number.(b) When the small piston is pushed in by 8.9 cm, how far is the car lifted? Enter a number. (c) Find the mechanical advantage of the lift, which is the ratio W / Fa. W / Fa Enter a number.

Answer:

Look at the outlet. It will have a number like NEMA 6- 20 R The '6' is a configuration the '20' is an ampere rating. Also check the circuit breaker. The Amp. rating on the breaker should match the outlet. For 15 or 20A, you need #12 copper wire. For 30 A. # 10. in Romex cable you want 3 # x + G. I haven't covered all the details. That wire needs to be properly supported, dry, and protected from damage. You can EMail with 'detail' questions.
Well it sounds like splitting the gas line will be easier but if you screw up BOOOM. For the electrical you will have to run a cable from the electrical box (where ever that is) to the dryer location. That is something most DIY types can do. You can't just change out an old outlet because the cable size will be wrong. That would lead to a fire. Not quite as bad a BOOOM. Note that you will still need a 120v outlet for the dryer. The heat comes from the gas but the motor that makes it spin is still electric.
(a) As pressures are the same on both the ends, F/(2.11)^2 9700/(10.5)^2 so,F185.64N
