A Class 1 lever is defined by the position of the fulcrum, which lies between the effort (input force) and the load (output force or resistance).
This principle applies regardless of whether the lever provides a mechanical advantage or disadvantage.
In Lever, mechanical advantage is the ratio of _______.
Which of the following is an example of a second class lever?
Which of the following is an example of a first class lever?
If we compare the effort arm length with the load arm length in a class 1 lever, ________
If we compare the effort arm length with the load arm length in a Class 2 lever, _______.
A pair of plier and scissor are together considered as a _______ Class 1 lever.
A ramp is used to lift a box to a platform 2 m high. To reduce the effort required, the ramp length is increased from 4 m to 8 m. Assuming negligible friction, what remains unchanged?
The effort in a class 1 lever is in __________ direction(s).
In a lever-operated compressor servicing tool (Class 1 lever), if the load arm length is decreased while the effort arm length is kept constant, what will be the effect on its mechanical advantage?
In Lever, mechanical advantage is the ratio of _______.
