How much does a robotics engineer earn?
The average salary of a robotics engineer is $52,857 per year. Some robotics engineers can earn up to $75,865 per year.
Difference between BS and EN Standards?
BS standards are british standards EN standards are European Union standards. For individual differences you would need to look at the particular standard you are concerned with. There are many thousands.
A compound machine is any type of machine that is made from two or more simple machines working together. A modern TV is not a compound machine since it has no moving parts.
What are uniformly varying loads?
udl is converted into point load by multiplying the value of udl with the length of the section of the beam over which the udl is acting.these converted point load is acted at the middle of the section.
Where we use positive displacement pumps?
A positive displacement pump causes a liquid or gas to move by trapping a fixed amount of fluid or gas and then forcing (displacing) that trapped volume into the discharge pipe. Positive displacement pumps can be further classified as either rotary-type (for example the rotary vane) or lobe pumps similar to oil pumps used in car engines.Moreover,these pumps give a non pulsating output or displacement unlike the reciprocating pumps and hence are called positive displacement pumps
Where could one purchase cast iron beds?
Cast iron skillets are found at many retail stores including Walmart, Bed Bath & Beyond, and Target. Additionally, if you prefer online retailers, then Amazon and Overstock also provide this product.
Accuracy because it tells us how close our value is to the accepted/expected value rather than precision that only describes reproducibilty and closeness of results to One another.
What is the invert level for manholes and inspection chamber?
the lowest level of outgoing orifice where there are numerous inlet & out pipes connecting a manhole.
How a work piece held to the lathe machine?
a laithe works by a rotating jaw with ur work in the chuck and u can use many laithe tools to cut difrent things off of your work sick bled dont mention
It has a head stock(fixed and is connected to motor) and a tail stock(movable).The tool is moved towards the workpiece (which is driven by motor).Used for making cylindrical sections,tapering,drilling..
What is the procedure for checking a lathe that the safety mechanisms function correctly?
make sure you test them before working on it
What are the characteristics of construction steel?
Yield strength is the most common characteristic of construction steel, it has a minimum yield strength of 275 N/mmâ_. Steel is also very tough and durable, it can withstand extremely heavy loads. It is also weldable and ductile.
What is the pressure rating for Schedule 10 steel pipe?
The fittings THREADED are normally rated for 125 PSI but there are ratings over 3,000 PSI if needed such as high pressure steam applications Then one has to take temperature /pressure relationship into consideration higher temperature greater pressure
"A hammermill is just a shredding device. There are different devices for different things, but pretty much any shredding device is considered a hammermill."
The interesting thing is that a hammermill can be used to shred Hammermill paper products.
Is there any difference in temperature at inlet and outlet of steam turbine?
For efficiency's sake, the outlet had best be a lot cooler.
Why a Rotary Engine is More Efficient than Piston System?
Having untangling that tangled grammar...
+++
I assume you understand the basics of both types of engine, despite not using the term "reciprocating".
+++
The steam-turbine is usually designed to expand the steam through its full pressure / volume / temperature range, so from high inlet pressure to a partial vacuum in the condenser, which reverts the exhaust stem to water for feeding back to the boiler.
+++
The turbine's steam flow is from inlet to exhaust through steady stages, so each part of the turbine is at a constant temperature; hence low thermodynamic losses. The rotor and inter-stage stator blades are designed to give as smooth a flow as possible while extracting the maximum turning-moment in each stage. The reciprocating engine (unless of uniflow type) uses the same passages between valve and cylinder for both live (inlet) and exhaust steam, hence creates alternating steam flows with a certain amount of wasteful heat-cycling.
+++
The turbine is entirely rotative, so develops equivalent power from much less moving mass, avoiding inertia and vibration problems. The back-pressure created on the exhaust stroke in a reciprocating engine is minimised but some is still necessary for mechanical cushioning against the high inertia of heavy piston, piston-rod, crosshead and connecting-rod as the stroke reverses. (Although their travel is a harmonic oscillation, which lessens the inertia to some extent naturally.) However it also loses power in compressing a small amount of used steam as the valve closes to exhaust and starts to open to inlet.
+++
To sum up, the inertial and internal-frictional mechanical losses, and the thermodynamic losses, in a turbine are far less than in a reciprocating engine of equivalent power.
How much weight can 14 gauge steel tubed bench hold?
If you're referring to 14 gauge steel wire, about 60-65 pounds safely, but remember, supported weight depends not only on the wire, but the screws and nails that are attached to the object and the wall or ceiling. (Not to mention the material of the wall or ceiling. Drywall will hold much less than hardwood, so use a stud finder if possible to drill/nail into the wall or ceiling for added support) When in doubt, always use stronger, thicker materials than you think you'll need.
Mechanism to transfer linear to rotary motion?
"Think of a simple single cylinder engine....crankshaft goes round & round,piston goes up & down,connecting rod keeps the two tied together...wa la!"
This type of linear motion is known as reciprocating motion, where the linear motion is a repetitive up and down, or back and forth action.
The linear motion velocity of a wheel and crank system is not uniform and conforms to a sinusodial curve, i.e. it is slowest at the 0º and 180º positions and fastest at the 90º position.
To get uniform linear motion from uniform rotary motion, you can use a threaded shaft and thread follower arrangement, or a rack and pinion.
btw, it's "voila!".

How are pneumatics better than hydraulics?
Poster below is correct. Air systems typically have a tank that is the analog of a hydraulic reservoir.[ebolton]
*****************
Actually there is need for air reservoir in industrial pneumatics systems.
Hydraulics can handle more powerful aplications than pneumatics for the same overall dimensions, or can be more compact for the same power.
What was the name of the first rocket built?
The first manmade object known to have been placed in Earth orbit was Sputnik 1 - a Soviet satellite. However, the first manmade objects to enter space sub-orbitally were arguably German A4/V2 ballistic missiles. These were being developed and launched from the Baltic island of Peenemunde from before WW2 and several thousand were fired in action before the close of hostilities. The standard A4 missile reached altitudes in excess of 50 miles, long considered the threshold of "space". After WW2 the United States continued to launch them experimentally from White Sands missile range. They created a two stage version, the "Bumper" which climbed to even greater altitudes and would be the safest contender for this title of first manmade object in space. Prior to 1950. It should be borne in mind that the question is rendered ambiguous by the fact that "space" has no distinct beginning. Whilst the International Space Station ( ISS ) orbits at about 200 miles altitude and most manned flight occurs there or lower, the upper regions of Earths atmosphere extend several thousand miles further! It is for this reason, resulting in subtle aerodynamic drag that such low orbits decay if the vehicle is not periodically boosted, as is the ISS by means of Russian Progress and Soyuz vehicles. It can therefore be argued that the earliest manmade objects in space were actually high altitude balloons. It is argued, moreover, that the first man in space was USAF colonel Joseph H. Kittinger, who made the highest human balloon ascent in history aboard Excelsior 3, from which he returned by parachute, on August 16th 1960. The highest parachute drop ever, wearing a space-suit and descending for several minutes before his chute could be opened.
What was the name of the largest tank battle in history?
The Panzerkampfwagen VIII, codenamed Maus("mouse" ... who says the Nazis didn't have a sense of humor?), was the largest tank ever built (as a prototype ... an additional hull without turret was also completed).
Larger tanks such as the Landkreuzer P-1000 Ratte ("rat"), about five times larger than the Maus, have been designed but never actually built. Even the Maus was really too large and unwieldy to be of any real practical use.
How do bicycle reflectors work?
The lens is made up of many tiny geometric shapes that reflect the light back to source rather than let the light through the lens. There is often a silvered coating on the reflector back to enhance the reflective properties of the lens.
