I believe that servo is motorized and solenoid is magnetically activated.

The fuel-oil mixture ratio for all Echo products is 50:1, or 1 gallon of GAS to 2.6oz of 2-stroke oil

The manufacture recommends a 20:1 ratio, 1 gal gas and 6.4 floz oil or if you use the special Echo oil a 32:1 ratio, 1 gal gas and 4 floz oil.

A diesel engine is an internal combustion engine which uses the heat of compression to ignite the fuel/air mixture in the third stroke of the 4-stroke cycle, while the petrol engine is an internal combustion engine which uses an electrically-generated spark system to do the ignition.

Diesel engines have a higher efficiency compared to petrol engines. In simple terms this means diesel engines can give 50% or more miles per gallon than petrol engines.

The strain theory is a state of deviation from bond angle of a normal tetrahedral angle.

The cylinder's intake valve opens to let in a pre-mixed dose of atomized fuel and air. The cylinder moves upward, squeezing this mixture from it's original size to about 1/8th of it's original size. At the top of the stroke, a spark plug is timed to fire, the spark of which ignites the fuel/air mixture causing it to burn rapidly (it does not explode, it burns), and produces a huge volume of gasses that forcibly push the piston back down - this energy is transmitted through gears to the wheels of the car.

54,000 psi is its ultimate breaking tensile strength.

Yield point is 36,000 psi

in JIS (Japanese) "SS" stands for structural steel, and 400 grade

which is similar to AISI 1018.

Angular momentum will not change unless an external torque acts upon the system

The short answer would be that angular momentum is conserved, i.e. it cannot be created nor destroyed.

A more technical answer would be that there is a certain theorem in theoretical physics called Noether's theorem which shows that if a physical theory exhibits rotational invariance (i.e. the physics are the same even if you rotate the system) that angular momentum conservation is a result.

According to particle physics therefore the conservation of angular momentum seems to tell us that the Universe is invariant under rotations. This might seem strange, because surely rotating yourself changes how think look, but the physics involved remains the same.

Plasma cutter is the most efficient method for all sizes and thicknesses. For thinner materials, carbide edged shears or snips are suffice. Band saws are another industry preferred method using 18tpi carbon based blades.

Spur gears have straight teeth while helical gears have curved teeth. Generally, helical gears are usually quieter and smoother in operation, while spur gears are easier to make and much less expensive.
Helical gears are stronger than spur gears.

Well the LSAW stands for Lick Sack Anus Warts, and EfsW stands for Erected Faggish Wenus pipe

Kindly inform which steel is the equivalent to a193 b7

The mechanical advantage is a numerical relationship among the sizes of

physical components of the machine. It's constant as long as the sizes

of those parts of the machine are constant.

It depends on how many times the rope 'goes around' the pulleys. If there are 2 ropes 'pulling up' then the mechanical advantage is double. Think about it this way: the tension throughout the rope is constant, so if the object being lifted is 100 pounds, but there are 2 ropes going up from the movable pulley, then each rope has 50 pounds tension on it, but they are the same rope, so you are pulling with 50 pounds force on the rope to create the 50 pounds tension.

Note that the pulley system reduces the amount of force necessary to lift, but the amount of work necessary is the same. Example: if you want to lift the 100 pound weight by 1 foot, you will use 100 foot-pounds of work. With the pulley system as described, you are exerting 50 pounds of force, and must pull the rope 2 feet to lift the weight 1 foot.

It depends on which aircraft you mean. A small model airplane might consume only a few ounces per hour, while a Boeing 747 consumes as much as 22,500 pounds of Jet-A per hour. There are hundreds of different planes in between, each with different burn rates.

No simple answer to that. Usually, simple is good, but there's limit to how much pressure you can build with a single-stage pump. A two-stage pump will let you reach higher pressures, but is more complicated.

There are all sorts of screw diameters - major, minor, pitch, mean, etc., but in general a screw diameter is a called by its nominal diameter which is the major diameter of the screw, approximately. For example a 1/2 inch screw has a nominal diameter of 1/2 inch.

The stem or the spine is the central structural beam of a ship.

some things to know about mechanical engineering relevant to the skills invovled are that you need to have good relationships with other people, got to be prompt, good use of hands, have a lot of time, enjoy the work, and eat 43 pickles from smelly socks

name three basic dimensions of orthographic drawing

A transient voltage is a time varying voltage value. Transient says that the voltage value changes, especially from a steady state, to a new value, then back again.

Yes . . .in order to reduce blade vibration and improved airflow characteristics . .

relative roughness is the average bump height divided by the same characteristic length (pipe diamter) the relative roughness is calculated by k/d, k=0.0015 and d being the diameter relative roughness is the average bump height divided by the same characteristic length (pipe diamter) the relative roughness is calculated by k/d, k=0.0015 and d being the diameter

Screw chiller running with a male & female blade,Centrifugual chiller running with an impeller.

Screw chiller are very reliable on more load like more than 200 tr ,its less consumption comapare to other chillers.
