First Class Lever. This is a type of lever which has the fulcrum in between the weight and the force applied. Its order is represented as force-fulcrum-weight. This is the most basic type of lever. Example: Our hand pushing an object or seesaws, crowbars. Using scissors represents the use of two first-class levers. A wheel and axle is also an ...

2023年11月21日 · A class 3 lever is a lever that has the input force in between the fulcrum and the load. Other examples of 3rd-class levers include baseball bats, lacrosse sticks, and golf clubs (and a bunch of ...

2018年6月8日 · see answer below Given: Give examples of 1st, 2nd and 3rd class levers 1st class levers: fulcrum is in the middle - seesaw - scissor - pliers 2nd class levers: fulcrum on one end, load is between the force and the fulcrum: - nail clipper - wheel barrel - bottle opener -stapler -nut cracker 3rd class levers: fulcrum on one end, effort is in the middle and force is on the …

A fulcrum (F) does not move but remains fixed when a lever is in use. Classification of levers: According to where the load and effort are located with respect to the fulcrum, there are three types or classes of lever: First-Class Lever, Second …

A Class 1 lever refers to when the fulcrum is located between the load and effort, and the load and effort move in opposite directions. A great example of a Class 1 lever is a teeter-totter. A teeter-totter involves a rigid bar that pivots at a fixed location in the middle of the bar (i.e. the fulcrum is located in the middle of the bar).

Q. Explain the difference between second class and third class lever. Q. Refer to the given figures, (A, B and C) and arrange them in an order of first class lever, second class lever and third class lever.

A fulcrum (F) does not move but remains fixed when a lever is in use. Classification of levers: According to where the load and effort are located with respect to the fulcrum, there are three types or classes of lever: First-Class Lever, Second …

The mechanical advantage of this class 1 lever is approximately 1.7. Example Problem 2 - Calculating the Mechanical Advantage of a Lever As shown above, a person uses a 3.0-m long bar as a lever.

In each class, the fulcrum, load, and effort are in different locations. Answer and Explanation: 1 In a second class lever, the fulcrum is on one end of the lever, the effort is on the other end, and the load is between the fulcrum and the effort...
