Gear 5 will run at 50 rpm and in a clockwise direction.
What is a gear train?
A mechanical system called a gear train is created by putting gears on a frame such that they mesh together. Gear teeth are made to guarantee that engaging gears' pitch circles move on each other without slapping, allowing for a smooth transition from one gear to the next.
Given that five gears meshed to each other running in a line. the first gear z=100, second gear z=50, third gear z=200, fourth gear z=150 and fifth gear z=200. the first gear turns clockwise at 100 revolutions per minute.
The speed of the fifth gear will be calculated as below:-
( 100/50 ) × ( 50/200) × ( 200/150 ) × ( 150/200) = 0.5
In an odd number of gears, the first and last rotate in the same direction.
100 rpm × 0.5 = 50 rpm
Therefore, gear 5 will run at 50 rpm and in a clockwise direction.
