Why migration is necessary in kiln?
Due to the difference in kiln shell outer and tyre inner diameter,kiln revalotion is more then tyre.The slippage of shell inside tyre is called migration.When tyre and kiln become rigid so the air gap become zero between both and migration get zero.Migration tell us only that there is air gap.actual air gap is necessery for shell expantion.
What is the force of 300 lbs falling 3'?
By "force", I assume you mean, 'what is the equivalent static load of an impact from a 300# object falling 3 feet'. What you have there is 900 ft-lb of potential energy. The force applied to the other body on impact is going to depend on the structure of both bodies. In the extreme case, people often survive car crashes, even without airbags, because the metal of the car deforms, spreading out the time of the collision so the person's body has much more time to slow down, reducing forces on it. Since F = M*A, more time to slow down means the absolute value of A is lower, which brings down the absolute value of F. How much force you will get from your 900 ft-lb depends on the nature of the object and the surface it's landing on. If both are very hard, the collision will be elastic and the force very high. If one or both is soft, not so high.
Can metal melt?
Yes, all metals, both pure (element) and alloys, can be melted; though some require large heat inputs at very high temperatures. By contrast the lowest melting point is of a lead-tin-antimony-bismuth mixture called "Wood's Alloy", at about 70ºC.
How is a lever similar to a wheel and axle?
It is similar because they both move...
Pipe A can fill tank in 30 mins and pipe B in 28 mins If 34th tank is filled by pipe B alone and both are opened how much time is required by both pipes to the tank completely?
pipe a fill 1/4th part in 7 mins and pipe b in 7.5 mins hence both tank will fill 1/4th of tank in 7+7.5/4 = 3.6 mins
When using hacksaw to cut a piece of metal the blade and and metal both become hot.explain in energy terms why this happen?
The chemical energy in the muscles of the person doing the sawing is transformed into mechanical energy at the tip of the saw teeth. As these abrade the metal the friction (rubbing of the two surfaces over one another) causes some of the the mechanical energy to be converted into vibrational energy at the atomic/molecular level in the substance of both the saw and the metal. This sort of vibrational energy is known as heat and both get hot.
Is a hack saw a compass saw or a dovetail saw meant to cut metal?
A hacksaw is meant to cut metal. -The other 2 mentioned, compass saw and dovetail saw are both for woodwork.
What is a piece of metal?
A metal is a chemical element that is a good conductor of both electricity and heat and forms cations and ionic bonds with non-metals. A piece is a part of or small portion of a larger object or material. A piece of Metal is therefore a small portion of a chemical element that is a good conductor of both electricity and heat and forms cations and ionic bonds with non-metals.
Will bleach harm automobile paint?
Yes, bleach can be harmful to both the metal and the paint on a car. Bleach is an oxidizer. This can cause the metal to become pitted and the paint to fade or become discolored.
