Agricultural Equipment and Their Uses
Agriculture has been transformed by technology to increase output and quality of goods. Today, farmers who are still breaking their backs using traditional agriculture tools are wasting their time. Tractor…
INTRODUCTION
All field crops need soil, water, air and light (sunshine) to grow. The soil gives stability to the plants; it also stores the water and nutrients which the plants can…
Work, Power and Energy
INTRODUCTION Whenever a force acts on a body, and the body undergoes some displacement, then work is said to be done. e.g., if a force P, acting on a body, causes it…
Balancing of Rotating Masses
INTRODUCTION We have already discussed in the last chapter about the centrifugal force. We know that whenever a body is rotating or attached to a rotating shaft, it is subjected…
Motion Along a Circular Path
INTRODUCTION We see that whenever a person, drives round a curve or a circular track on a bicycle or a motor cycle or a scootor, he has to lean inward…
Collision of Elastic Bodies
INTRODUCTION We daily see children playing with balls of glass, rubber and other elastic materials. If we see them carefully, we will find that if a glass ball is allowed…
Helical Springs and Pendulums
INTRODUCTION We have already discussed in chapter 23 the simple harmonic motion of bodies without any reference to the force causing such a motion. But in this chapter, we shall…
Motion of Connected Bodies
INTRODUCTION In the previous chapter, we discussed the motion of a body, when it is subjected to some external force. But in this chapter, we shall discuss the motion of…
Laws of Motion
INTRODUCTION The entire system of dynamics is based on three laws of motion, which are the fundamental laws, and were formulated by *Newton. Like other scientific laws, these are also stated…
Simple Harmonic Motion
INTRODUCTION In the previous chapters, we have discussed the motion of particles or bodies in a straight line or in rotation. But in this chapter, we shall discuss the motion…
