Define lever
is a bone and is shown as a straight line
is a pivot or joint and is shown as a triangle
is a force provided by muscles and is shown by an arrow
is the weight of the body/object being moved, it is shown as a square
Define fulcrum
is a bone and is shown as a straight line
is a pivot or joint and is shown as a triangle
is a force provided by muscles and is shown by an arrow
is the weight of the body/object being moved, it is shown as a square
Define effort
is a bone and is shown as a straight line
is a pivot or join and is shown as a triangle
is a force provided by muscles and is shown by an arrow
is the weight of the body/object being moved, it is shown as a square
Define load
is a bone and is shown as a straight line
is a pivot or joint and is shown as a triangle
is a force provided by muscles and is shown by an arrow
is the weight of the body/object being moved, it is shown as a square
Define mechanical advantage
a large load can be lifted with a relatively small amount of effort
levers cannot lift as heavy a load with the same effort, due to the position of the effort and load from the fulcrum
Describe mechanical advantage in relation to 1st and 2nd class levers
strong and stable and allows a load to be moved with relatively small effort
strong and stable and allows a load to be moved with large muscular effort
provides speed and a wide range of movement
Mechanical advantage occurs when...
the fulcrum is between the effort and the load
the effort is between the fulcrum and the load
a lever's effort arm is longer than its load arm
a lever's load arm is longer than its effort arm
The effort is another name for
The muscle
The bone
The weight
The lever
The fulcrum is another name for the
ligament
muscle
joint
bone
If the fulcrum is closer to the load than to the effort, there will be a mechanical (a) .
Class 3 levers operate at mechanical (a) .
