What does a belt and pulley system allow for?
- correct answer mechanical power, torque, and speed to be transmitted across axles
How is mechanical advantage realized?
- correct answer if the pulleys are different diameters
what is a pulley?
- correct answer a wheel on an axle or shaft that is designed to support movement and change of
direction of a cable or belt along its circumference
Why are pulleys used?
- correct answer lift loads
apply forces
trasmit power
What is usually the drive element of a pulley?
- correct answer rope, cable, belt or chain that runs over the pulley inside the groove
Pulleys are assembled to form what
- correct answer a block and tackle in order to provide mechanical advantage to apply large forces
rope and pulley systems (block and tackle) are characterized by what?
- correct answer the use of a single continuous rope to transmit a tension force around one or more
pulleys to lift or move a load
