Class `I` lever is that in which

Class-two levers

Class III levers have mechanical advantage less than 1. why are they then used ?

The diagram alongside shows a lever in use : To which class of levers does it belong ?

The diagram below shows a lever in use : To which class of levers does it belong ?

The diagram below shows a lever in use. (a) To which class of lever does it belong ? Give one example of this class. (b) How will the mechanical advantage of lever change if load is shifted towards the fulcrum without changing it's dimensions.

Class II levers are designed to have :

Figure below shows a lever in use (a) To which class of levers does it belongs ? (b) Without changing the dimensions of the lever, if the load is shifted towards the fulcrum what happens to the mechanical advantage of the lever ?

The class of lever in which the load is located between the fulcrum and the effort

Which class of levers has a mechanical advantage always greater than one? What change can be brought about in this lever to increase its mechanical advantage?

The diagram below shows a rod lifting a stone. (a) Mark position of fulcrum F and draw arrows to show the directions of load L and effort E. (b) What class of lever is the rod ? (c) Give one more example of the same class of lever stated in part (b). .
