Mechanical Engineering

There is electronic pumps and mechanical pump. Electronic pumps are run using an electronic EPU assy. mainly used outdoors because it does not need to have open air passages to cool itself. Mechanical pumps need fans to cool them so outdoor use is not recommended. Then there are diaphragm pumps vs. peristaltic pumps. Diaphragm pumps pushes chemical through valves that open and close to force chemical into a pressurized water line. The peristaltic pumps push chemical through a tube that is being squeezed by rollers.

Efficiency=Useful energy output divided by the energy input. i.e. 100 J is the energy input and you get 5 J light energy from a lamp, the waste energy would be 5 J.

u know that big tank in front?well water i is turned to steam in the boiler then pushed into the big tank and pushes that giant steel/iron rod out the the steam leaves sucking the rod in and steam is again pushed in and so on,moving the wheels forward or backward.

The air conditioning system was made to provide a cooling effect to those who were uncomfortable in the heat and humidity. Back in the days, it was used for the same purpose it is now used for.

A currency counting machine that a bank uses has an electronic eye that sorts the bills according to denomination. The machine can count paper money relatively fast as long as all of the bills are facing the same way.

The generally accepted consensus is that oil is organic. This, however, is only a theory.

An opposing theory is that oil's origin is abiotic. According to this theory, oil is an inorganic substance created deep in the mantle, and is much more plentiful than we believe.

Some scientists say both theories are correct and that there are two different kinds of oil.

About 70%. Not every distance between places is small, and public transport probably does not go everywhere.

We could look at eccentric loading on a crane as the weight or load that is off the vertical axis of the crane. There are lots of different cranes, but let's dive in, bounce around a bit and speak in general terms. We'll start by taking a look at what a crane does and consider our options. A crane is designed to lift loads up, which is a simple but necessary start. Cranes generally have a boom extending out from the central axis of the crane. Now focus on this. The mass of the boom will be acted on by gravity and "pulled on" while it's sticking out. And the straighter it sticks out, the more the effect on the crane. That is, the more the mass of the boom will be acting to try to pull the crane over. And that's with no load. Let's do something crude but that might help. Pick up a broom near the end of the handle. Hold your arm straight out and hold the broom straight up in the air. You can feel the mass of the broom. Now lower the broom to where it is sticking straight out from your arm. There is a greater torque on your shoulder now because you're holding the broom straight out. Let's jump a bit now to look at a special type of crane. The tower crane, which is used in the construction of tall buildings, has a movable counterweight. That allows the operator to "balance" the effect of the load and the effect of the counterweight. They'll offset each other to pretty much eliminate any eccentric loading. Obviously the tower crane can't handle much of that without being ripped off the structure to which it is attached. Simple and effective. Think this through a moment before moving on. Got it? Good. On the "back" of a "regular" crane is a counterweight to offset the mass of the boom. Without the counterweight, the boom may tip the whole machine in the direction the boom is pointing. Recall that when we stick the boom out straighter, it tends to "torque" the crane off its vertical axis more. Why wouldn't it? The counterweight is doing its job. But there is no perfect match here between the mass in the counterweight and the boom. That's because as the boom is lowered or raised, the "effective mass" of the boom changes, even with no load on it. Now let's do a "pick" with the machine. A pick is a lifting operation. When we set up a crane, we generally have what are called outriggers to spot. These are "legs" that extend out from the crane and have a "foot" on them that is hydraulically shoved down on cribbing. These outriggers make the lifting platform more stable, and you can see why. The effective "footprint" of the machine is much greater with the outriggers set. We're ready to do a pick. When we hook up a load and lift it, the operator will be trying to keep the boom as "straight up in the air" as possible. This will minimize that "off-center loading" or eccentric loading. He's got the knowledge, skill and experience to use the machine in a way that will prevent eccentric loading from permitting a safe pick.

Do you mean used? Please be a little more specific, for example, What engines are used in aircraft, What instruments are used in aircraft.

bronze is easier to melt. steel is stronger than bronze and most importantly, its much lighter than bronze so you don't get tired swinging or even carrying the weapons. maybe that's why bronze armor is not used since it's super heavy.

Both are a means of delivering water at an increased pressure. The difference between the two is how they are installed. The water pressure in an elevated water tank system increases as the height of the tank goes higher. As a simple example, get a length of transparent plasticÊhose and fill it with water. Hold both ends of the hose at level then slowly raise one end higher than the other. Water will flow towards the lower end. For a booster pump system, there is no need for elevation. The pump itself is capable of increasing the pressure by pushing water fasterÊusing a hydraulic valve system.

Electric wires are manufactured in various ways. One of the most common methods is the strip twist where wires are enhanced to hold mechanical loads.Ê

what is the fullform of EPDM The full form of EPDM is Ethylene Propylene Diene Monomer and it is a synthetic rubber with excellent stability. It has resistance to ozone and UV effects, heat and has good colour fastness (reduces colur fading).

Compared to 304 grade stainless steel, the 316 has higher strength, can withstand higher temperatures, and yes it can resist corrosion better. One factor is the molybdenum content in the 316 grade which gives it the overall corrosion resistant properties. The downside, 316 stainless steel grade is way more expensive than 304.

A reciprocating engine is different than when using rotors. Rotors are used in a pistonless rotary engine, using one or more rotors and sometimes called rotary pistons.

Capillary tube is a very simple device and can be manufacture easily at low cost. The capillary tube can limit the maximum amount of refrigerant to be charged eliminating the need for a receiver in the refrigeration system. Another advantage is when the refrigeration plant is stopped, the pressure along the capillary tube and the entire system remains constant which means that if the compressor is restarted it does not need moreÊpower to overcome high pressure in the system. Hence, smaller compressors can be used instead of big, expensive ones. A disadvantage with capillary coil is that this system is non adjustable due to the fact that the control of the flow of pressure is dictated by the inside diameter of the tube.

0.25 to 0.3 depends on the steel

It is easier.

The question is not complete enough to be answered. The word EASIER needs to be further defined. so the question should read: What is easier to [add information here]; more screw threads or less screw threads?

I think they used a horse and carriage although you needed a licence to do any of this as it susposedly stopped the travel of diseases.

The MV-22, better known as the Osprey, falls into the category of a tiltrotor aircraft. This means that it takes off like a conventional helicopter but has the capability to convert its prop-rotors to a position like a turbo prop airplane. It is designed to get military troops into small landing zones but be able to get them to and from one location in a timely manner, just like an airplane. The Marine Corps has the MV-22 and the Air Force has the CV-22. The Osprey is a troop transport and has been deployed to Iraq and Afghanistan.

no they are caused when hot exhaust gases hit the cold air,known as a vapor trail
