Total questions: 10
Worksheet time: 5mins
To increase friction between the tires and the road
Horsepower is the amount of torque needed to stop a moving car
Horsepower is the amount of torque needed to accelerate a car
Which statement about gear size and speed is true?
larger gears spin faster becasue they create an optimum gear ratio
larger gears spin faster becasue they are able to generate more leverage
smaller gears spin faster because their smaller radius means less linear distrance to travel
smaller gears spin faster because their lower weight makes it easier to spin them
Which arrangement will increase torque?
small driver gear and equal size driven gear
large driver gear and smaller driven gear
small driver gear and larger driven gear
large driver gear and equal size driven gear
A driven gear is spinning faster than the driver. What's going on here?
the driver gear is smaller
the driver gear is larger
the driven gear has more teeth than the driver
the driver gear has less teeth than the driven
In a manual transmission car, why do lower gears have higher gear ratio?
To save gas
To make sure the wheels spin faster
To make turning easier in low gears
To get the car going and increase acceleration
The increase in torque with larger gears is similar to what simple machine?
Wedge
Lever
Inclined plane
Screw
