PULLEYS AND GEARS

Hi Students!!!


Here a picture of how the direction of gears work which we have talked about in class and a few examples that you can use to try to figure out the direction various gears move.



REMEMBER- Whatever direction the first gear or the driver goes, the gear connected to it goes the OPPOSITE direction!!



Practise on this example:


Which way does the 2nd gear (on the FAR right) go if the 1st gear (on the FAR left) starts turning COUNTERCLOCKWISE? What about the 3rd gear (the bottom gear)?
