5'3 = 5.25 feet = 1.6002 m

Algebraic Steps / Dimensional Analysis Formula 5.25 ft*12 in

1 ft*2.54 cm

1 in*1 m

100 cm=1.6002 m

Direct Conversion Formula 5.25 ft*0.3048 m

1 ft=1.6002 m

Both were NEW, SLOW, and UNRELIABLE. Tanks were used to break thru barbed wired trenches; and planes were originally used for aerial reconnaissance (scouting) and artillery spotting (adjusting fire).

So there are more possibility to fit the wrench.

Wind turbines are usually 100-120 m high above the ground.The height is usually fixed based on the diameter of the blades.But if the height increses the available wind power increases yielding more power.But the cost also increases.So based on the diameter of blades height is decided.usually for a 80m dia blades the height ranges between 100-120m

I think you are refering to the 'section modulus' which is a geometrical property of a cross section. it is the moment of inertia divided by the distance from the centroid or neutral axis to the farthest point of the section. this modulus measures flexural resistance.

The flow of oil in an hydraulic system can be compaired to any water system; in both systems you will find the tank (place where the liquid is store), the conduits or channels through which the liquid will travel (pipes), the pump (to impulse the liquid through long distances or to de a job such as filling a cylinder (piston) or pushing hot or cold water through an air conditioning system in a building, filters (to ensure purity of the liquid), and finally you may have temperature controls. The oil characteristics of a hydraulic system are such that permits the oil to perform amazing work such as keeping a building structure level (this is the case at the outshore airport of Tokyo, which keeps sinking into the see bed and by means of hydraulic systems they turn the support of the structure hydraulic jacks as needed to keep the whole airport level.

The brakes in any car is another example of a hydraulic system where the flow of oil impulse by the brake pedal and or the ABS pump will force the pads of the brakes grab the wheel discs hindering the wheels from turning.

The power steering in any car is another example of oil flowing trough pipes to help the driver turn the car around.

Divide kN by 9.806649 i.e. 100kN / 9.806649 = 10.197 tonnes

The term DBB is mostly used to define a level of isolation that is provided by valves in a pipeline or process system. The term is used to describe a safe method of isolation from a pressurized or hazardous medium to facilitate breaching of the pressure system for maintenance and modification. The terminology is also utilised to identify the relative of temporary isolation system.

to find the velocity of water in a pipe use the equation

Q = VA

where

Q = the total volume of water running through the pipe in cubic feet per second

V = the velocity of the water

A = the cross sectional area of the pipe.

(remember area = r^2*pi or D^2/4*pi). If you have the radius in inches find the area in inches and divide by 144 (1 square foot) this will yield the area in ft^2.

you need to know how much water is running through the pipe (Q) - say 5 cfs and the area of the pipe (A) - say 1 ft^2

rearrange the previous equation V = Q/A and you get V = 5cfs/ 1 ft^2 = 5 fps

It can duplicate itself.

Yes it will bring down the fatigue life and the material will not endure at any point. Degrading nature of fatigue loading on the materials is compounded by the corrosion interaction. Synergistic damage - The damage will be more than the addition of damages due to corrosion and fatigue loading. The formation of intrusion and extrusion due to fatigue loading leads to the notches. The corrosion media will enter the notches and forms oxide with the base metal and it will be passive to further corrosion. But the fatigue loading will disturb the passive layer and facilitate the media to corrode the fresh material. Hence it will drastically decrease the fatigue life of the material.

It depends on which polyamide. Try rephrasing the question.

The ASTM equivalent of DIN 1543 is ASTM A572. Both of these materials are a type of carbon steel.

A bulkhead is a nautical term for a "wall" in a ship. It is a structural element and a load bearing division of a vessel, and it can run beam to beam or fore and aft. Bulkheads could separate something like the grain storage compartments in a barge, or could run along either side of a passageway on a cruise ship. A baffle may provide some structural support, but it is a partition with holes in it. We'll see baffles in something like the fuel tanks of large ships. The baffles will inhibit the movement of fuel from one side of the vessel to the other as it rolls in seas, and this will increase stability dramatically.

Essentially the first internal combustion engine was invented in the late 1600's (the specific year is unknown) by the English inventor Sir Samuel Morland. The engine ran on gun powder and was used mostly for pumping water.

In 1860 the Belgium inventor, Lenoir, designed an engine that some consider the first Internal Combustion Engine, because it ran on a mixture of air and coal dust and was ignited by an electrical spark. In 1863, the engine was revised to include a carburettor and burn liquid petroleum gas. The engine was use to move a three wheeled cart, but most commonly it was used as a stationary power plant for printing presses, water pumps, and machine tools.

Cable systems provide rates of approximately 500 Kbps downstream and 128 Kbps upstream. Theoretically they can provide a bandwidth of 30 Mbps. A DSL system can provide speeds of up to 7.1 Mbps, but most providers offer a maximum of 1.5 Mbps upstream and downstream.
