In the process of changing a flat tire, a motorist uses
ahydraulic jack. she begins by applying a force of 45n to theinput
piston, which has a radius r1. as a result, theoutput
plunger, which has a radius, r2, applies a forceto the
car. the ratio r2/r1 has a valueof 8.3.
ignore the height difference between the input pistonand output
plunger and determine the force that the output plungerapplies to
the car.

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
