what is a pulley? - ANS-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? - ANS-lift loads
apply forces
trasmit power
What is usually the drive element of a pulley? - ANS-rope,
cable, belt or chain that runs over the pulley inside the
groove
, Pulleys are assembled to form what - ANS-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? - ANS-the use of a single
continuous rope to transmit a tension force around one or
more pulleys to lift or move a load
the rope may be a light line or a strong cable
What is the mechanical advantage of a rope and pulley
system if it does not dissipate or store energy? - ANS-the
number of parts of the rope that act on the load
What is a lever? - ANS-a machine consisting of a beam or
rigid rod pivoted at a fixed hinge or fulcrum
A belt and pulley system is characterized by - ANS-two or
