FLYWHEEL AND GOVERNOR Introduction:- In the steam or I.C. engines, the fluctuations of turning moment exerted on the crankshaft are reflected in fluctuations of the speed of the crankshaft. The flywheel is used to control the fluctuations in speed during each cycle of an engine. lt a rotating mass which 1s attached to the …
Diagram shows the principal parts of an I.C. engine. The details regarding the various parts of the engine are as follow: Cylinder Cylinder head Piston Rings Connecting rod Crank Crank case Valves Cams Flywheel Cylinder: It is the cylindrical vessel in which the fuel is burnt and the power is developed. It is considered as …
Vacuum braking system is a system which uses only the vacuum for the application of brakes. WORKING OF VACUUM BRAKE SYSTEM The brakes are always in released condition with vacuum unit the driver pushes the brake pedal. In this condition position of piston cap is in cap end of the brake cylinder and cam is …
DIFFERENCE BETWEEN SINGLE And MULTI PLATE CLUTCH The number of pairs of contacting surfaces in the single plate clutch is one or at the most, two. There are more number of contacting surfaces in the multi-disk clutch. As the number of contacting surfaces is increased, the torque transmitting capacity is also increased, other conditions being …

Multi plate clutch consists of more than one clutch plates contrary to single plate clutch which consists of only one plate. Friction surfaces are made in case of multi-plate clutch. Due to increased number of friction surfaces, a multi-plate clutch can transmit large torque. Therefore, it is used in racing cars and heavy motor vehicles …

TWO-STROKE CYCLE DIESEL ENGINE DIAGRAM FOUR-STROKE CYCLE DIESEL ENGINE DIAGRAM DIFFERENCE BETWEEN TWO-STROKE AND FOUR-STROKE CYCLE DIESEL ENGINES A brief but critical comparison of the merits and limitations of the two-stroke-cycle diesel engine compared with the four-stroke power unit is made below. Theoretically, almost twice the power can be developed with a two-stroke engine compared …

DIFFERENCE BETWEEN TWO-STROKE AND FOUR-STROKE CYCLE PETROL ENGINES The following remarks compare the main points regarding the effectiveness of both engine cycles. The two-stroke engine completes one cycle of events for every revolution of the crankshaft, compared with the two revolutions required for the four-stroke engine cycle. Theoretically, the two-stroke engine should develop twice the …

WHAT IS A SOLAR TREE? A solar tree is a decorative means of producing solar energy and also electricity. It uses multiple no of solar panels which forms the shape of a tree. The panels are arranged in a tree fashion in a tall tower/pole. TREE stands for T= TREE GENERATING R=RENEWABLE E=ENERGY and E=ELECTRICITY …

Answer: Stress is a measure of the load applied to a sample relative to a cross sectional area of the sample. Strength is a quantification of the samples ability to carry a load. The terms “yield strength” and “yield stress” of a material are usually used interchangeably (correct or not). It is the stress which will …

Answer: Both terms are same when gravity is uniform. When gravity is non-uniform following are the terms: The centre of mass is a point that acts as if all the mass was centered there (the mass on one side of the point is equal to the mass on the opposite side). If supported at the centre …
