hi guys, Don't think that this is going to be so easy, if you want your reward you will have to be more clever... you will have to cut a wire if you hit the right wire you will be able to continue, if you fail you will have to prove that you are good enough to enter the academy.

Calculate the gear ratios and the velocities of the driven pulleys if the motors turn at 600 rpm, and also describe the motions.

DATA

SOLUTION

ndriven = Rt × ndrive = 1 × 600 = 600 rpm

Ddrive= 9cm

R t= 9 / 9 =1

R t= D drive / D driven

well done guys!!!

ndrive= 600rpm

ndriven= ¿?

Ddriven= 9cm
