What is the definition of output force?
outputforce: the force the lever applies to the load
How are levers grouped?
Levers are grouped by where the fulcrum, load, and effect force are found.
Tell you about levers and their effort and load?
The load is the weight and the effort is the movment. The effort is the force applied, and load divided by effort is mechanical advantage.
What are 1 class levers?
Lever belongs to the category of simple machines. They are three types of levers 1. First class levers 2. Second class levers 3. Third class levers In the first class levers fulcrum is in between applied force and load. common examples are Crowbar , Pair of scissors , SeeSaw , Skull and neck in our body .
What is the definition of phantom load?
A load that is not really there.
What is the definition of output force?
outputforce: the force the lever applies to the load
How are levers grouped?
Levers are grouped by where the fulcrum, load, and effect force are found.
How do levers work?
levers work by having a effort that lifts a load, and a fulcrum balances the two
What are some examples of class 3 levers?
First class levers are like see-saws. The fulcrum (turning point) comes between the effort and the load. So if you push down on the effort the load goes up. With second class levers the load comes between the effort and the fulcrum. This is good for catapulting things. Third class levers have the effort between the load and the fulcrum. An example would be a fishing rod. The fish on the end is the load, your hand on the rod is the effort and the hand at the end is the fulcrum.

What makes the first class lever second class lever third class lever different?
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.
What is the definition of phantom load?
A load that is not really there.
How is mechanical advantage calculated for levers?
lenght of the effort arm divided by lenght of the load arm
Examples of first class levers?
first class levers have fulcrum at center and load and effort at extremes, examples are seesaw and scissor.
Where is the first class lever located?
First levers always follow the order: Load fulcrum effort/force. The load is at one end of the lever and the force is applied at the other end. The fulcrum is somewhere in between the load and force. Scissors are examples of 1st class levers or when elevating one's head above one's chest.
Why Wheel Barrow is second order lever?
because the load is in between the effort and the fulcrum. In second order levers the load is always in between the effort and the fulcrum.
