From times immemorial, man has used machines to help him in his work. Today, we are dependent on machine for almost every task. When we think of machines we always tend to think of big and complicated units with many moving parts like wheels and rollers..

It consists of a steel cylinder, filled with a highly concentrated solution of sodium hydrogen carbonate. At one end is a small receptacle made of strong wire netting. A glass bottle, containing concentrated sulphuric acid is placed inside the receptacle. Just near this bottle is a metal knob, part..

In all the above examples, a machine either multiplies or reduces the effect of the force that is applied. A bicycle is a machine which is used to gain speed. We gain speed by exerting additional force. When we try to ride a bicycle up a steep hill, we soon realize tha..

The transmission of power is made use of in hydraulic machines where a small force applied at one point is made to exert a much larger force at some other point. This principle is made use of in the working of a hydraulic press and hydraulic brake..

Summary - Machine is a device that is used to multiply force, or to gain speed, or to change the direction of a force, or transform energy. Levers, pulleys, inclined plane and gears are some of the examples of simple machines..

For the manufacture of bleaching powder, glass, calcium carbide, soda ash etc. For white washing of buildings. For tanning of leather. As a fertilizer for acidic soil. For softening hard water. In building and construction industry as an important raw material..

The length of a machined part is to be 8.5 cm, with a tolerance of 0.04 cm. Express the tolerance limit as an absolute value inequality. (Use the variable n for the actual measure of the part in cm.) => | n - 8.5 | < 0.04 or | n - 8.5 | ≤ 0.04 or | n + 8.5 | < 0.04 or |..
