Mechanical Engineering

Brass is alloy of copper and zinc. There are a lot of brasses worldwide with different copper and zinc content and with addition of other elements.

The drive axle's location depends on whether the automobile is front or rear-wheel drive. It is somewhat more complex than a dead axle because it comes in two halves, with a multi-ended joint connecting the two. This joint is called a constant velocity or CV joint. It connects to the driveshaft, a rod which extends from the automobile's transmission, which is connected to the automobile's engine. As the driveshaft turns, the motion is transferred to the drive axles via the CV joint. This causes the wheels connected to the ends of the axle to turn. While 4-wheel drive vehicles have two drive axles, all automobiles must have at least one drive axle to function.

Pneumatics have been used for thousands of years, ever since hunters used the blow-gun to take down their prey.

Amazing stories

Mechanical advantage is not the only reason to use levers.

brine is salt and water usually 100% saturation

salt and water freezes at about zero degrees F (non toxic) but rather hard on steel or iron.

ethylene-glycol and water at 50/50 mix is about -60 f (very toxic) good with metals

propylene glycol and water 50/50 about -40 and a bit toxic good with metal

brine is rather cheap salt $30/ton

if you live near an ocean and have a bucket real cheap

all the others are from big oil and expensive but dont hurt metal

water has the highest specific heat of common materials and as such is the best refrigerant

A "faying edge" is the edges of two materials that are to be joined. This is the surface of a member in contact with another member to be welded.

Density is mass/(volume) while weigh is mass/(gravity).

Examlpe: A ton of iron and a ton of straw weigh the same (a ton) but take up different amounts of space due to different densities.

i got 105 marks in aieee what is the expected rank

A high carbon And High Chromium steel is called HCHCr material.Normaly consists carbon of 2% and Chromium of 12% Silicon and Manganese vary between 0.2-0.35%

This is a direct hardening material and can be hardened to 58-60 HRC.

This material is used for manufacturing press tools and sheering blades.

It depends on many parameters. Generally between 3 to 5 Tonnes per Hour.

Different types of injection machine, the cost is different, also it is depended on the injection machine brand. the machine elements , system , sparts parts and so on are the basic of the injection mahcine. what's more, the product material also influents the mahcine, if you make the PET preform mould, you need to bu PET injection machine ....

Probably not, how long did it run before the mix up was discovered? All of the refrigerant has to come out and be properly disposed of, then a good evacuation and recharge. You did not say which refrigerant was the correct one for the machine, but either way it all has to go.

Take 550mm divide it by 2 to get the radius. Square the value of the radius. Muiltiply that value with 960 and 3.14. You now have your volume of the cylinder in mm. To convert from mm to cm. Divide the value you got by 10. Volume of any cylinder = (Pi) x (radius)^2 x (height).

a pivot and a geometrical ment

This looks like the beginning of a question - but it never gets around to the question. Without a question being asked, it's pretty hard to provide an answer.

For the benefit of anyone who stumbles upon this non-question, I'm guessing that they might have been looking for the work required to supply 1 KW of heat to the reservoir of a system where the COP is 5.

COP is the acronym for "coefficient of performance". It is defined as COP = Q/W where Q is the heat supplied to or removed from the reservoir. If Q is 1kw and the COP is 5, then it would take W = Q/COP = 1 kW/5 = 0.2 kW of work to supply that heat.

I would recommend draining the entire fuel system and re-filling it with pure diesel. I do know some guys that add a gallon or two of gasoline to their diesel trucks, meaning big rig semi's, in the winter for easier starting, however their truck's fuel tanks have a 50 gallon capacity. Diesel is a lubricant as well as a fuel. Running gasoline, or a high mixture of gasoline WILL cause SERIOUS damage to a diesel engine. So my advice would be to get it out.

To add a different perspective, the Mercedes manual for the older Mercedes cars says you can safely run up to 30% regular gasoline mixed in your diesel fuel - mostly for winter, as stated above. Most diesels would be safe at near this level of mix. But at the ratios mentioned in the question looks like only a 15% mix. This should be safe, especially as a one time deal. As you run some out, just add more diesel when you can. Much better than wasting the 46 liters of fuel! Don't panic. Add a couple ounces of 2 stroke oil if it makes you feel better.

Yes,because somebody like me.

It's joining two pieces of metal together, either by adding a 3rd molten metal at the joint, or by melting the metals themselves until they fuse together.

Do note that there are a few similar methods for joining metals called brazing and soldering. What's what is determined by which temperature the process is performed at.

Wire lifting is the moving of wires on a movable wire trellis system, mostly to a higher position on the trellis to support vineyard vigour and thereby to support canopy structure.

I dont think you can increase the speed of the motor but if the motor is driving some piece of rotating equipment (pump etc) the speed of the driven shaft can be increased up to the point where the motor reaches full load current.

Elements subjected to loading or subjected to force.

Your feed rate depends on the pitch of the thread i.e. 16 TPI =a feed rate of .0625

To cut a double lead thread you need to either rotate the part 180 deg. for the

second thread or change the start point by pitch /2

1/16=.0625 .0625/2= .0312 so your second thread will start .0312 from the first thread.

the main advantage of flitch beam is to strengthen the beam and decrease the deflection (∆) in the beam by decreasing elasticity (E) because the elasticity of steel is much bigger than a wood beam. their ratio is about 15 to 20 (n=15 to 20).
