AP Torque

Find the magnitude of the torque produced by a 5.0 N force applied to a door at a perpendicular distance of 65 cm from the hinge.

• 75 Nm

• 3.25 Nm

• 6.3 Nm

• 8.75 Nm

If the torque required to loosen a nut on the wheel of a car has a magnitude of 60.0 N• m, what minimum perpendicular force must be exerted by a mechanic at the end of a 45.0 cm wrench to loosen the nut?

• .666 Nm

•  133.3 N

• 66.7 N

• 13.3 Nm

A wrench is used to tighten a nut. A 15N perpendicular force is applied 50cm away from the axis of rotation, and moves a distance of 10 cm as it turns. What is the torque applied to the wrench?

• 7.5 Nm

• 1.5 Nm

• 750 Nm

• 150 Nm

A force in a circular direction

• Reciprocating

• Torque

• Speed

• Oscillating

When speed increases, what happens to the value of torque?

• increases

• decreases

• stays constant

What is torque?

• Torque is a measure of the linear force applied to an object.

• Torque is a unit of temperature measurement.

• Torque is a type of musical instrument.

• Torque is a measure of the force that tries to rotate around an axis

What direction is the torque acting with respect to post A?

• clockwise

• Counter clockwise

• Neither Direction

• Depends on the mass of the diver

What is the distance the masses on the right of the fulcrum need to be to balance with the two masses on the left?

• .65 m

• .56 m

• .79 m

• .39 m

A rod on a horizontal tabletop is pivoted at one end and is free to rotate without friction about a vertical axis, as shown in the diagram.  A force F is applied at an angle θ to the rod.  If F were to be applied perpendicular to the rod, at what distance from the axis should it be applied in order to produce the same amount of torque?

• L sin θ

• L cos θ

• L 

• L tan θ

When gears are equal in size, what happens to the speed and torque?

• Speed increases; torques decreases

• Speed decreases; torque increases

• Speed and torque are constant
