Answer:

There will be three (3) states that will be needed in-order to implement the FSM controller.

Explanation:

FSM stands for Finite-State Machine. This is an example of a model used in mathematical computation. The FSM is an abstract machine that can be in exactly one of a finite number of states at any given time.

Describe a gear train that would transform a counterclockwise input rotation to a counterclockwise output rotation where the dri

masya89 [10]

Answer:

For a gear train that would train that transform a counterclockwise input into a counterclockwise output such that the gear that is driven rotates three times when the driver rotates once, we have;

1) The number of gears in the gear train = 3 gears with an arrangement such that there is a gear in between the input and the output gear that rotates clockwise for the output gear to rotate counter clockwise

2) The speed ratio of the driven gear to the driver gear = 3

Therefore, we have;

$Speed \ Ratio =\dfrac{Speed \ of \ Driven \ Gear}{Speed \ of \ Driver \ Gear} = \dfrac{The \ Number \ of \ Teeth \ of \ Driver \ Gear}{The \ Number \ of \ Teeth \ of \ Driven \ Gear}$

Therefore, for a speed ratio of 3, the number of teeth of the driver gear, driving the output gear, must be 3 times, the number of teeth of the driven gear
