A simple gear train is composed of three gears. Gear A is the driver and has 84 teeth, gear B has 60 teeth, and gear c has 42 teeth. If gear C rotates at 60 rpm, how fast is gear a rotating?

A simple gear train is composed of three gears. Gear A is the driver and has 84 teeth, gear B has 60 teeth, and gear c has 42 teeth. If the output at gear C is 1200 ft. lb, what is the input torque at gear A?

A compound gear train is composed of four gears: A, B, C, and D. Gear A has 120 teeth. Gear B has 12 teeth and shares a shaft with gear C, which has 24 teeth. Gear C is meshed with gear D, the output gear. Power is supplied at gear A with 200 ft. lb of torque and is traveling at 400 rpm. The necessary torque output for the system is 1600 ft. lb. What should the gear ratio of the system be?

In a pulley system, pulley A is moving at 600 rpm and has a diameter of 12 in. Three pulleys B, C, and D, all of different sizes are attached to a single output shaft. Speed and torque output are changed within the system by moving the drive belt between pulleys B, C, and D. A speed of 1200 rpm is required when the drive belt is connected to pulley B. What is the diameter of pulley B?

In a pulley system, pulley A is moving at 600 rpm and has a diameter of 12 in. Three pulleys B, C, and D, all of different sizes are attached to a single output shaft. Speed and torque output are changed within the system by moving the drive belt between pulleys B, C, and D. A speed of 800 rpm is required when the drive belt is connected to pulley C. What is the diameter of pulley C?

What is one difference between gears and sprockets?

Two meshed gears will rotate in the same direction as each other.

Two sprockets in a chain drive will rotate in the same direction as each other.

In a gear system, the gear (or sprocket) attached to the power source is called what?

In a gear system, the gear (or sprocket) that is moved as a result of the drive gear is called what?

Another word for drive gear is:

Another word for DRIVEN gear is:

How do we indicate the size of gears and sprockets?

A gear or gears that go in between the drive gear and the driven gear are called what?

What is the measurement of force applied in a linear motion?

What is the measurement of force applied in a circular motion?

Are these gears increasing Speed or Torque?

Are these gears increasing speed or torque?

Speed and torque have an inverse relationship. Meaning you have to give up one for the other.

You can dramatically increase or decrease the speed of your robot tires by using a compound gear system?
