  • 1st order levers have the fulcrum between the load and effort arms. The mechanical advantage of these levers can be greater or less than 1, depending on the length of the arms.
  • 2nd order levers have the load portion between the effort portion and the fulcrum. These always have a mechanical advantage greater than 1. They increase the force exerted at the expense of distance.
  • 3rd order levers have the effort portion between the load portion and the fulcrum. These always have a mechanical advantage less than 1. They decrease the force exerted with a gain to the distance.

Is a wheelbarrow first class lever second class lever third class lever or fourth class lever?

A wheelbarrow is a second-class lever. In a second-class lever, the load is between the effort (force) and the fulcrum, which allows for a mechanical advantage in lifting and moving heavy loads with less effort.


First Second and Third class levers are determined by the location of what?

The location of the effort, load, and fulcrum determine if a lever is a first, second, or third-class lever. In a first-class lever, the fulcrum is between the effort and the load. In a second-class lever, the load is between the fulcrum and the effort. In a third-class lever, the effort is between the fulcrum and the load.


What is the difference between a first class and a second class lever?

The main difference between a first class and a second class lever is the relative placement of the effort, load, and fulcrum. In a first class lever, the fulcrum is positioned between the effort and the load. In a second class lever, the load is between the fulcrum and the effort. Examples of first class levers include a seesaw, while examples of second class levers include a wheelbarrow.


How are second and first class levers differentiated?

A First Class lever is one in which the fulcrum is locatedbetween the effort and the load.A Second Class lever is one in which the load is locatedbetween the fulcrum and the effort.A Third Class lever is one in which the effort is locatedbetween the fulcrum and the load.


What are the disadvantages of a SECOND class lever?

The main disadvantage of a second-class lever is that it requires a greater force input compared to a first-class lever to move the load. Additionally, the load is located closer to the fulcrum, which can limit the range of motion of the lever.

How does a first-class lever different from a second-class lever?
