Which kind of movement is depicted in the picture?

• Rotary
• Linear
• Oscillating
• Reciprocating

The product of the force times the lever arm; the movement of the force about the axis is:

• torque

• lever arm

• rotational inertia

• angular momentum

The formula used to find a torque is...

• (m)(g)

• (F) cos(Ɵ)

• (F)(r)( sin $\theta$  )

• (m)(a)

The easiest way to open a heavy door  is by applying the force

• Near the hinges
• In the middle of the door
• At the edge of the door far from the hinges
• At the top of the door
