___________ is best defined as the measure of the force that can cause an object to rotate about an axis

• rotational motion

• torque

• mechanical advantage

• work

The more wheels, the better the control

• True

• False

Say you're designing a sumobot, but the wheels happen to have too much tread. What would this lead to

• increased risk of getting stuck

• increased torque

• increased speed

Decreasing the diameter will decrease the torque of the wheels but make it harder to turn

• True

• False

Answer explanation

Decreasing the diameter of the wheel does in fact decrease the torque, but it actually makes it easier for the robot to turn. This is because less force is required to turn the wheel

If the red gear is the driver gear, then that would mean there is a decrease in torque but an increase in speed

• True

• False
