What is the significance of gear ratios in mechanical systems?

• They determine the speed and torque output of the system.

• They increase the weight of the system.

• They reduce the efficiency of the system.

• They are used to measure temperature.

What is the effect of a gear ratio of 1:2 on speed and torque?

• It increases speed and decreases torque.

• It decreases speed and increases torque.

• It has no effect on speed or torque.

• It increases both speed and torque.

What is the relationship between gear ratio and torque?

• A higher gear ratio increases torque but decreases speed.

• A higher gear ratio decreases torque and increases speed.

• A higher gear ratio has no effect on torque or speed.

• A higher gear ratio increases both torque and speed.

What is a gear?

• A toothed wheel that can change the direction, torque, and speed of rotational movement.

• A type of engine used in vehicles.

• A device that measures speed and distance.

• A component used for electrical connections.

• 1:3

• 2:1

• 3:1

• 1:2

What is the gear ratio of a 15-tooth driver gear and a 45-tooth driven gear?

• 1:2

• 2:1

How do you calculate gear ratio using the number of teeth?

• gear ratio = (number of teeth on driver gear)/(number of teeth on driven gear)

• gear ratio = (number of teeth on driven gear)/(number of teeth on driver gear)

• gear ratio = (number of teeth on driven gear) + (number of teeth on driver gear)

• gear ratio = (number of teeth on driven gear) - (number of teeth on driver gear)
