Using a lever means that you need to use less effort for a maximum effect. A wheelbarrow is a classical example of being able to move a heavy load, using the wheel as the fulcrum.

How are levers grouped?
Levers are grouped by where the fulcrum, load, and effect force are found.
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.
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.
Whats the definition of load as it applies to levers?
the weight of the force being applied.
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 .
How do levers work?
levers work by having a effort that lifts a load, and a fulcrum balances the two
What is the major factor controlling the manner in which levers work?
The difference in the positioning of the effort, load, and fulcrum.

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.

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 is the impact on productivity when employees get late to work?
· It will develop a conflict situation between the employer and employee. · Decrease the work duration in an oganization. · Breakdown of work · Last production · Overtime for others · Work load for others · Financially lost · Decrease in employee moral · Decrease in overall productivity
Whats the definition of load as it applies to levers?
the weight of the force being applied.
What are the description of lever?
A lever is a simple machine that makes work easier for use; it involves moving a load around a pivot using a force. Many of our basic tools use levers, including scissors (2 class 1 levers), pliers (2 class 1 levers), hammer claws (a single class 2 lever), nut crackers (2 class 2 levers), and tongs (2 class 3 levers).
How Lever works?
Levers are force multipliers so the effort, the imput force, can produce a larger force on the load. Levers use moments to work. M=Fxd Here's an example: You use a force of 5N to lift a load. The lever causes your hand to be 1m away from the pivot of the lever. The moment is 5Nm. The load is 0.2m from the pivot. Rearrange the equation and you should find: F=M/d --> F=5/0.2=25N Hope this helped!
How are first and second class levers different?
the first class levers have the fulcrum in the middle and the resistance and effort on the two sides second class levers have the resistance in the middle and the fulcrum and the effort on the two sides
