Examples of Class Two Lever: All classes of levers have four basic parts: Beam- The lever, a wooden plank or metal bar resting on the fulcrum. Fulcrum- the pivot or the turning point. Force- the effort or input needed to move the beam and load. Load- the item or object being moved ...
What is a second class lever?Levers:In the field of physics, a lever refers to a stiff/rigid bar that pivots at a fixed location, which is known as a fulcrum. Additionally, there are loads and efforts applied to this bar. There are three main types of levers (Class 1, 2, and 3)...
To determine which class of lever should be preferred to use a machine as a force multiplier, we can follow these steps:1. Understand the Concept of Levers: A lever is a simple machine that consists of a rigid bar that pivots a
Levers are inflexible, rigid bars that are used to do work. They are one of the six kinds of simple machines. Levers turn, or pivot, on a fulcrum. There are three different classes of levers. In each class, the fulcrum, load, and effort are in different locations....
Classify the following into levers as class I, class II or class III: (a) a door (b) a catapult (c) claw hammer (d) a wheel barrow (e) a fishing rod
In a third class lever, the effort is between the load and the fulcrum. Some examples of third class levers includefishing rods, cricket bats and chopsticks. Third class levers are different from first and second class levers because instead of force multipliers, they are speed multipliers. ...
Draw a diagram of a second class lever, identify sporting examples, answer some exam questions on second class levers and describe an advantage of a second class lever. Why is this such an important topic to think about? We learn in relation to what we already know. ...

The interconnection can be made more easily when there is, either integral with or around the housing, an envelope incorporating a pair of second- class levers which, when squeezed together by ones fingers, deform the housing. The extremities of the levers can be formed to permit the connector...
