PASS.
A belt and pulley system is characterized by -
...ANSWER...two or more pulleys in common to a belt.
FCTC WRITTEN TEST
What does a belt and pulley system allow for? -
...ANSWER...mechanical power, torque, and speed to
be transmitted across axles
How is mechanical advantage realized? -
...ANSWER...if the pulleys are different diameters
Why are pulleys used? - ...ANSWER...lift loads apply
forces
trasmit power
,What is usually the drive element of a pulley? -
...ANSWER...rope, cable, belt or chain that runs over
the pulley inside the groove
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
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
What is a lever? - ...ANSWER...a machine consisting of
a beam or rigid rod pivoted at a fixed hinge or fulcrum
How do levers work? - ...ANSWER...amplifies an input
force to provide a greater output force, which is said to
provide leverage
Pulleys are assembled to form what - ...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? - ...ANSWER...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
Class 1 Lever - ...ANSWER...Fulcrum in the middle the
effort is applied on one side of the fulcrum and the
resistance on the other side.
Examples of Class 2 levers: - ...ANSWER...Wheel
barrow, a nutcracker, a bottle opener or the brake pedal
of a car
What is the mechanical advantage of a Class 2 lever? -
...ANSWER...It is always greater than 1
Class 3 Lever - ...ANSWER...Effort in the middle
The resistance is on one side of the effort and the
fulcrum is located on the other side.
Examples of Class 3 levers - ...ANSWER...tweezers or
, the human mandible
Mechanical advantage is always less than 1
FRE 123 - ...ANSWER...Fulcrum in middle for 1st
class
Resistance is in the middle for the 2nd lever
Effort is in the middle for the 3rd
what is the mechanical advantage of a lever? -
...ANSWER...the ratio or the output force to the input
force
How are levers classified? - ...ANSWER...by relative
positions of the fulcrum and the input and output forces.
allows identification by the relative locations of the
fulcrum, the resistance, and the effort.
HEAD - ...ANSWER...pressure created by the force of
gravity and is a function of the difference in elevation
between intake and output
