Principal of Lever

It states that the product of an effort with effort arm is equal to the product of load with load arm. Load x Load arm = Effort x Effort arm  . . .

Levers of the first order

In this type of levers, the fulcrum is situated between the load and the effort. The effort arm may be equal or less than or more than load arm. In case the effort arm is more than load arm, a small effort is required to more load. However, if effort arm is less than load arm, a large effort is required to move load.  Examples: Sea saw, Sci . . .

Pulley

Pulley is a flat circular disc having a groove in its edge and capable of rotating around a fixed point passing through its central axis commonly called axle. In a way axle is a fulcrum around which pulley rotates. . . .

Types of Pulley

Pulley consists of two types: 1. Single Fixed Pulley System: It consists of single pulley. It is attached to some high platform and around its groove passes a rope. One end of the rope is attached to the load. Effort is applied at the other end of the rope. This pulley is commonly used in drawing water from village wells.   2. Sing . . .

Functions of a Simple Machine

In most of the machines, the load is greater than the effort, However, in some machines, the load is equal to the effort or less than the effort but in such cases, the effort acts in a desired direction or at a convenient point which makes the job easy. Machine has the following two functions: 1. It changes the magnitude of the force required, i.e . . .

Simple Machines with Examples

Following are the six simple machine swhich are generally use in our daily life: 1. The lever  e.g. mango cutter, beam balance etc. 2. The pulley e.g. pulley  3. The wheel and axle e.g. door knob steering wheel etc. 4. The inclined plane  e.g. staircase, ramp etc. 5. The wedge e.g. needle, axe etc. 6. The . . .
