There are three types of levers namely first, second and third class. First class levers can change the direction of input force.

It is used where cost is a big factor but high strength is still required.

Yes an elevator is a movable pulley!

For a wire classified under American Wire Gauge standards, 26 gauge wire is 0.0159" (0.40386 mm) in dameter.

For a wire classified undere metric wire gauge standards, a 26 gauge wire is 2.6mm in diameter. Metric gauges are calculated simply by multiplying the diameter, in mm, by 10 and therefore increase as the diameter increases, unlike the AWG standard.

A fathom is a nautical measurement equal to 6 feet.

A material is considered ductile if it can be stretched or deformed without breaking. Ductility is the ability of a material to exhibit plastic deformation under tensile stress before fracture occurs. Materials like metals, such as gold and copper, are known for their ductile properties.

Milling machines are tools that can be hand or power driven to machine a variety of materials, incorporating dynamic movement and orientation to achieve superior tolerances.

yes it is

They are powered by compressed air, supplied via an air-hose under high pressure from an electric or petrol engined compressor.

Harder than work piece

High thermal conductivity

High heat transfer coefficient

Same as any other material. Glass has a thickness,inertia, area, modulus, etc. like all materials.

If u mean strength of glass, ask again

Rotating axial compressor.

Babalo

Autodesk makes many software that can do that.

An example of a substitutional alloy is sterling silver, which is a mixture of silver and copper. In this alloy, copper atoms replace some of the silver atoms in the crystal lattice structure, resulting in a material with improved strength and durability compared to pure silver.

The main thing that happens when there is water in diesel fuel is that it will burn poorly or maybe not even at all. It will also sink to the bottom of the fuel tank.

Only if you're in another spacecraft, and the sound would be more of the shockwave than the actual explosion.

That's not correct. You would neither hear nor feel it as there is nothing to transmit the sound or shock-wave (essentially the same thing, a compression-wave through a medium). Your own craft might be hit by debris though.

A pilot hole can be to help direct a screw in situations where alignment is important. Most commonly it is used to ease the process of fastening the screw and reducing potential damage to threads in the process.

== == Carbide generally describes a group of materials characterized by high hardness and metallic properties. Carbide cutting tool can cut a material which is having 60 HRC steel. Find the below link to know more about carbide cutting tools. www.ceratizit.com Rasheed.

I have experience when my team welded "JIG Ladle" A36 to AISI 4140, we used electrode E7018 with SMAW process. The important thing for this welding's prehating during welding min. 180 degree celcius and did peening the weld beads to minimize residual stresses. After welding covered by blanket for slow cooling. Regards, Asep S (asep93st@yahoo.com)

Shunt means parallel only..................

N is the symbol of Nitrogen, and nitrogen is NOT a metal

Vapour compression refrigeration systems have several disadvantages, including energy inefficiency, as they often require significant electrical power to operate compressors. They also rely on refrigerants that can have high global warming potential and may contribute to ozone depletion if leaked. Additionally, these systems can be complex and costly to maintain, as they involve moving parts that are susceptible to wear and tear. Finally, they may not perform efficiently in extremely high or low ambient temperatures.

At normal room temperatures, mercury has a low vapor pressure combined with a high mass, which makes diffusion pumping more efficient.
