Classical and Quantum mechanics are the two main fields of mechanics in physics. Classical mechanics came a few hundred years before Quantum mechanics. Subsequently it is less accurate and less reliable then the more recent mechanic field of Quantum mechanics. Despite being outdated‚ Classical mechanics can still be used for many everyday problems with bigger and slower moving objects. However‚ when dealing with extremely fast moving or small subatomic particles a Classical approach will not

Fluid Mechanics Report Instruction Water turbine is a very common used throughout the world to generate power. Although the concept of the Impact of a Jet is essentially simple‚ and it can has a highly hydraulic efficiency‚ the factor of how can produce a powerful reaction force back is also has to be considerate truly. If we can manage well‚ we can determine the best situation and the optimum deflection angle out‚ for getting the optimum force that the impact can produce. But first of all‚ we

1.1 If the Sun should suddenly explode (it can’t) how long would it take for us to notice the event? * According to scientists we have at least 5-6 million years before the sun would ever die out or explode. However if a phenominon like that were to occur there are diffent theories to what might happen. It would take light from the explosion eight minutes to travel the 93 million miles from the sun to the earth. However‚ Newton’s Law of Gravity claims that Earth would suffer an immediate departature

The objective of the lab was to learn about fracture mechanics. Fracture mechanics is the branch of structural mechanics that deals with mechanical behaviors of bodies containing flaws. Some important attributes of flaws are size‚ shape‚ and location/orientation relative to the stress field. Procedure: The primary tools for the lab consisted of 10 ceramic tiles and a Instron machine. The Instron machine was initially set up for 3-point bending by a technician. The base and thickness of the tile

Force: This can be defined as a pushing or pulling action that causes a change of the state of a body. A long jumper who wants to increase their degree of force will need to increase their weight‚ but this can negatively affect their speed‚ so it is vital to get the balance right. The law of reaction also applies to movements that occur in the air. In these situations the equal and opposite reaction is shown in movements of other parts of the body. A long jumper‚ for example‚ will bring the arms
