different simple machines

Simple Machines - 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 ste..

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 that we gain speed by applying greater force. It is impossible to multiply both the force and gain the speed at the same tim..

1.Glycerides The triglycerides are esters of glycerol with long chain fatty acids. Fatty acids always have an even number of carbons and may be saturated e.g, palmitic acid (C 1 5 H 3 1 COOH) and stearic acid (C 1 7 H 3 5 COOH) or unsaturated e.g., oleic acid (C 1 7 H 3 3 COOH) and linolenic..

Heart Lung Machine - Before surgeons can perform open-heart surgery or heart transplants or even to correct a simple heart defect, they have to be able to open up the heart and expose the chambers. To enable this, circulation and respiration are maintained by the heart - lung ..

Naming of Simple Compounds - Compounds formed by the combination of two different elements are called binary compounds. Example: CO, CCl 4 , H 2 S, NaCl, NH 3 , HBr. Binary compounds may be ionic or molecul..

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..

Let us now find out how Time Period of oscillation vary with time. Set up a simple pendulum and measure the time taken for 10 oscillations of the simple pendulum for different lengths like 10,20,40,60,80 and 100 cm. Time period of a pendulum varies with the length o..

The sales of a local electronic goods store in a particular month is shown in the bar graph. What was the difference between the sales of washing machines and refrigerators during that month? => 40 or 20 or 10 or 30..

P & R washing machine manufacturing company conducted tests on different models of washing machines before launching them into the market to know the weights (in kgs) they can withstand for a particular drum size. The results are 6, 5.5, 7, 8, 6.3 and 7.2. Find the sta..
