Difference between first class and third class lever
Answers
A lever that has its fulcrum (point of support or axis of rotation) between the point of resistance (load) and the point of effort (applied force). In the human body, a first class lever is used when the head is raised off the chest
A third-class lever is another example of a simple machine comprising a beam placed upon a fulcrum. In third-class levers, the fulcrum remains at one end of the beam—however, the force of the effort is now located between the fulcrum and the force of the load.
Answer:
Explanation:
in a first class lever the effort (force) moves over a large distance to move the load a smaller distance, and the fulcrum is between the effort (force) and the load. ... With third class levers the effort is between the load and the fulcrum, for example in barbecue tongs.
