VERIFIED ANSWERS|ALREADY GRADED A
1. A belt and pulley system is characterized by - (ANSWER)two or more pulleys in
common to a belt.
2. What does a belt and pulley system allow for? - (ANSWER)mechanical power, torque,
and speed to be transmitted across axles
3. How is mechanical advantage realized? - (ANSWER)if the pulleys are different
diameters
@#$%^& ()_)( &^%$%^& ()_+
4. what is a pulley? - (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
5. Why are pulleys used? - (ANSWER)lift loads
6. apply forces
7. trasmit power
8. What is usually the drive element of a pulley? - (ANSWER)rope, cable, belt or chain that
runs over the pulley inside the groove
9. Pulleys are assembled to form what - (ANSWER)a block and tackle in order to provide
mechanical advantage to apply large forces
10. rope and pulley systems (block and tackle) are characterized by what? - (ANSWER)the
use of a single continuous rope to transmit a tension force around one or more pulleys to
lift or move a load
11. the rope may be a light line or a strong cable
12. What is the mechanical advantage of a rope and pulley system if it does not dissipate or
store energy? - (ANSWER)the number of parts of the rope that act on the load
13. What is a lever? - (ANSWER)a machine consisting of a beam or rigid rod pivoted at a
fixed hinge or fulcrum
14. How do levers work? - (ANSWER)amplifies an input force to provide a greater output
force, which is said to provide leverage
15. what is the mechanical advantage of a lever? - (ANSWER)the ratio or the output force to
the input force
