What is the major factor controlling how levers work?
Explanation: Lever is the simple machine that has ability to rotate on its own in accordance with point.It is based on the working that is carried out by the different position load,force and fulcrum factors. These factors decide the movement and location the lever tends to move and work.

What is the major head flexor muscle?
The major head flexors are the sternocleidomastoid muscles, with the help of the muscles attached to the hyoid bone.
What is the first class lever?
First class levers have the fulcrum between the force and the load. In using a screwdriver to lift the lid from a paint tin you are moving the effort over a greater distance than the load. Other examples of first class levers are pliers, scissors, a crow bar, a claw hammer, a see-saw and a weighing balance.
What are the levers that operate at a mechanical disadvantage?
Third class levers always have mechanical disadvantage. Despite operating at mechanical disadvantage, third class levers are able to increase the distance covered and, therefore, the speed at the end of a lever arm. They can produce a larger range of movement with relatively low effort.
