A class three lever is where the load is one side of the force and the fulcrum is on the other side of the force. An example is a pair of tweezers. Another example is the secondary lever in a pair of fingernail clips, i.e. the part that closes on the fingernail. (The first lever in a pair of fingernail clips, i.e. the part that you press on, is an example of a second class lever.)
well one lever is a bat to play ball with it another one is a log it is used to stiff another one is something I'm not sure of sorry i know only two
Fishing pole.
Three classes Three
There are three different Classes of levers. Class One Levers have a fulcrum in the middle. Class Two Levers have a resistance in the middle. Class Three Levers have effort in the middle.
classes 1 and 2
i forgot but if you get mad please firgive me but dusews
two
first class The point about which a lever rotates is called the fulcrum
on the position of the fulcrum
There are multiple classes of levers, which can be used for varying situations. For example, some can be used for lifting tools, whereas others can be used for pulling large amounts of weight. Often, it is not otherwise possible to move large amounts of weight without these varying uses of levers, which speaks to their usefulness.
You can make foam balls on speaker output Model . This will be related to sound. You can make a little tiny see-sawwith a movable pivot, and use it to illustrate the three classes of levers, and to demonstrate how work energy is conserved in the operation of levers.
Well Levers are a simple machine that was created by someone special. Levers help us make work easier. GO LEVERS!!!! Well Levers are a simple machine that was created by someone special. Levers help us make work easier. GO LEVERS!!!!I always found it interesting that there are three classes of levers:1st class: The exerted force (Fe) is on the opposite side of the fulcrum (F)of the resulting force (Fr). For example, a pry bar.Fe-----F-----Fr2nd class: For example, a wheelbarrow:F-----Fr-----Fe(the fulcrum is the wheel)3rd class: For example a baseball batFr-----Fe-----F(the fulcrum is your hand)A fingernail clipper is a compound lever. It has a 2nd class and a 3rd class.A see-saw provides good fun. Although you might not think so your knives, forks and spoons are levers. You have the brake and gear change levers on a cycle. You might not be aware that there are three basic types of levers. Many switches are levers. Your own body has quite a few "bone" levers. When you flick a small ball of paper by using your ruler you are using a lever. You use a lever called a spoon to stir with. A bedroom door is a lever, as are most hinged things.Increasing force by mechanical advantage.>Mechanical advantage = distance moved by input / distance moved by output>Output force = input force * mechanical advantage>Force * distance = work done>(Input) force * distance = (Output) force * distance
A claw hammer is a lever when using the claw to pull a nail. A crowbar or pry bar is also a lever. Automobile friction jacks are also levers. Your arm is a biological (biomechanical) lever.
Well, there are three classes of levers. Class one levers are seesaws, where the effort force is on one end, fulcrum in the middle and object on the other end moving the opposite direction of the effort force. Class two levers are wheelbarrows, where the effort force is on one end, the fulcrum on the other and the object in the middle. Class three levers are like baseball bats, the fulcrum is on one end, the effort force in the middle and the object on the end. Other examples include: a golf club, catapult, an arm, a door, a tennis racket, a fly swatter or a stick.
