Mechanical Engineering

The issue is that diesel engines, while they produce a whole lot of torque, cannot rev nearly as high as comparable gasoline engines. And since:


horsepower = (torque*engine speed) / 5252


If your engine won't rev past 3000 rpm, you'll always have less peak horsepower than torque. As for why they can't rev higher, they're limited by either the burn rate of the fuel per ignition stroke, the mechanical limitations due to the longer piston rods/crank lobes, or both.

Numerous types of belts having different nomenclature are available in the market. For example ; belts having trapezoidal teeth, circular teeth, inch series, metric series. To know all, visit following link ;

Internal and external chills are equally effective when used for the purpose for which they are intended.

A a rare combination of low weight and high strength

The process to make finger nails is very simple. The body converts nutrients and vitamins into the nail that grows.

Simply speaking The Calculus is a branch of mathematics that deals with amounts of change over certain periods of time.

Viscosity should be within +/- 10% of original value (i.e. no lower than 40cSt for a 46cSt lube oil product)

Water is usually done with a crackling test the result should be negative.

Suggested limits for additives and wear metals (sodium, copper etc) can be found at www.vibronurse.com just check out the lube oil section.

For good long term running particle count should correspond to 4 using NAS-1638 standard. Vibronurse provides a free tool for converting between ISO4406 - NAS-1638 - SAE Grade and actual particle numbers (http://www.vibronurse.com/particles.html).

Alloying of metals can be done to

a. Prevent rust(corrosion)

Ex. Chromium and nickel added to iron to form stainless steel. The chromium can form an oxide layer that can prevent iron from oxidise(rust). Suitable to make fork, spoon, and others.

b. To make it harder (hard to shaped)

Ex. Carbon is added to Iron to form steel. Steel is very hard, however brittle also. Suitable to make bridge, cars body, pipe and etc.

Ex. Aluminium is very light but very malleable. When it is added with copper and magnesium, it form duralumin. It is very hard, withstand corrosion and light. Its suitable to make an airplane body.

c. To improve the appearance

A normal metal usually gets dull when it exposed to air, water and uv light in a long time. To create an attractive surface and look, metal such neckel and chromium were added. Ex. Nickel were added to copper to form an alloy named cpro-nickel such alloy were used to make coins attractive and shiny.

ASTM covers a vast number of standard. Each standard or specification is identified by unique identifier that starts with a capital letter follow by one to four digits. The standards listed under "E" represent "Miscellaneous Subjects." For a complete list of ASTM designation see the "Related Links."

Very simple The Reversible Process: That type of process that work cycle, it mean to complete revolution and come back to the initial point from where it start. Example are Carnot Cycle. Two and Four stroke engine.

Irreversible Process: Opposite to reversible process called irreversible process.

Example are Electricity

7 ways. 1 you go to amazon.com and buy a key. 2 you may be able to pick it with a small screw driver. 3 you hire a lock smith from the yellow pages. 4 pop the pins out of the hinges with a hammer and screw driver or nail sink. 5 you may be able to take the lock apart. 6 you pry the door open with a crow bar. 7 try the old credit card trick

the traps designed use was to hold a " plug " of water, to help stop sewer odors from backing up the pipes.

SCF = Volumetank x (PSIgtank+PSIatmosphere)/(PSIatmosphere) x (Tstandard)/(Ttank) note that PSIg is your gage pressure of the tank, PSI atmosphere is accepted to be about 14.7 and the temperatures are to be in absoloute (Rankin) and the volume of the cylinder should be in cubic feet. without specifics, it's hard to give an answer to what you are asking, but you should be able to easily figure it out from here.

the cc stands for cubic centimeters, so 1200 cc is the total displacement of the engine.

It is the total volume, that the cylinders would displace for each stroke.

For example. Suppose you have 4 cylinders in an engine. If each cylinder displaces 300cc for each stroke ( from Top dead centre to bottom dead centre), then it equals 1200cc for 4 cylinders.

folding over 180 degrees and flattening, thereby creating a hem.

Im going to tell you how to fix a broken frame. First, you need loctite glue, and a protractor. Get your broken glasses, and frame. Put the glue on the tip of the broken frame. Measure the frame to 90 degrees. Then glue it on. Wait for about an hour or two. Then tada! You have a good frame on your non-broken glasses! Hope this helped. :DDD

There are quite a few metals that elevators are made out of. These elevators could be made out of stainless steel for example.

Tables are made from wood or plastic.
