Overview

Machine can change the direction of the force with the goal that force can be connected in an convenient manner. A machine can be anything which can assist us with doing some work and which can make our work simpler, faster, and effortless. Load , Effort, Mechanical Advantage, Velocity Ratio, Work Input, Work Output, Efficiency are a portion of the specialized terms utilized when we talk about machines.

Basic Requirement

  • Class 10 Student

Skills Covered

  • Block And Tackle

  • Single Fixed Pulley

Notes for ICSE Class 10 Physics Chapter 3 Machines

Revision is necessary for conceptual understanding and for securing good marks, and Revision Notes are always considered the best. ICSE Class 10 Physics Chapter 3 Machines Revision Notes are one of the most useful study materials that students can have, as they help them to study better and reduce the level of stress they face during the hectic year.

Here at Teacherdada, we provide courses for ICSE Class 10 Physics Chapter 3 Machines Revision in an easy-to-understand manner, providing the most effective training for such a crucial topic.

A machine can be anything which can help us to do some work and which can make our work easier, faster, and effortless.

It is a device which helps us to lift heavy loads, speeds up the motion or changes the direction of force in the desired direction.

Load ,Effort, Mechanical Advantage, Velocity Ratio, Work Input, Work Output, Efficiency are some of the technical terms used when we talk about machines.

A simple machine is a basic device that alters the magnitude and/or direction of a force.

Some examples of simple machines are levers, inclined planes, and pulleys.

A lever is one of the most common types of simple machines we use. It is a rigid bar, which can be rotated about a fixed point. Levers are used everywhere, from door handles to sea saws, scissors, punching machines, and more.

we will learn in detail about machines, related technical terms, and also about simple machines like Levers.

Machines

By applying a small force (or effort) at the appropriate point and in the desired direction we can either overcome a large resistive force (or load) or we can increase speed.

Principle of a Machine

When energy is supplied to a machine by exerting effort, it performs useful work.

The point at which the machine receives energy by applying effort is called the effort point

Load point is the point at which energy is obtained by overcoming the load

Input energy = Work is done at effort point = Effort × displacement of the point of application of effort

Output energy = Work done at load point = Load × displacement of the point of application of load

Ideal and Actual Machine

A machine that loses no energy in any way is an ideal machine. The output energy of a machine is always less than its input energy.

The reasons are:

1. It does not have weightless moving parts nor does it move smoothly.

2. If there is a string in it, it is not perfectly elastic.

3. Each part of it is not perfectly rigid.
