Thin wires resist electricity more or less than thick wires?

A thin (smaller diameter) wire resist more electricity than a thick (larger diameter) wire. Just like a larger pipe will allow more water to flow than a smaller pipe, a larger wire has more cross-sectional area to allow more current to flow.


What are helicle gears?

helical gears offer a refinement over spur gears. The leading edges of the teeth are not parallel to the axis of rotation, but are set at an angle. Since the gear is curved, this angling causes the tooth shape to be a segment of a helix. The angled teeth engage more gradually than do spur gear teeth. This causes helical gears to run more smoothly and quietly than spur gears. Helical gears can be meshed in a parallel or crossed orientation. The former refers to when the shafts are parallel to each other; this is the most common orientation. In the latter, the shafts are non-parallel. For a crossed configuration the gears must have the same pressure angle and normal pitch, however the helix angle and handedness can be different. The relationship between the two shafts is actually defined by the helix angle(s) of the two shafts and the handedness, as defined: : : Where β is the helix angle for the gear. The crossed configuration is less mechanically sound because there is only a point contact between the gears, whereas in the parallel configuration there is a line contact. Quite commonly helical gears are used with the helix angle of one having the negative of the helix angle of the other; such a pair might also be referred to as having a right-handed helix and a left-handed helix of equal angles. The two equal but opposite angles add to zero: the angle between shafts is zero -- that is, the shafts are parallel. Where the sum or the difference (as described in the equations above) is not zero the shafts are crossed. For shafts crossed at right angles the helix angles are of the same hand because they must add to 90 degrees.


Is it more expensive to add an extra level or a basement to existing house?

Basement. There will be much more planning, re-inforcing, damp proofing and ventilation requirements as they will be under the main structure which they have to secure befor they can start the dig out process


Working of oldham's coupling?

An Oldham coupling is a flexible shaft coupling that consists of two hubs (each with a fin or tenon) and one midsection (with grooves that fit those fins, one on each side of the midsection, and perpendicular to one another). The Oldham coupling is an outstanding design for torque transmission between two shafts which might be slightly misaligned. The coupling accommodates this misalignment, while maintaining homokinetic motion (the two shafts rotate at the same speed at all times), and while exerting only very small reactive forces (resistance to accommodation of the misalignment, exhibited as sideward forces on the shafts). More information on Oldham couplings can be found at www.oepcouplings.com.

How can you find more information about ventilation systems?

One can find more information about ventilation systems in several ways. First, one could research ventilation systems through ventilation system installers. Also, one can find more information about ventilation systems through blogs.

What is cross ventilation?

ventilation with more than one direction. If your home or office has windows on the north and south (or any two different directions), it has cross-ventilation.


Straight or curved string trimmer?

Straight shafts have more power and a longer reach (for under trees etc) but are heavier. Curved shafts are lighter and have less power but are cheaper.


Why did people invent positive numbers?

Positive numbers were originally invented so that we could tell how much we have of something. For example, how many arrow shafts do we have, and how many stone arrowheads do we have to put on our arrow shafts? By answering those questions we can tell whether we need to make more shafts, or more heads. It's very practical.


Whats the difference between a graphite and a steel shaft for golf clubs?

Graphite shafts transmit fewer vibrations up the shaft to the golfer's hands than do steel shafts. This might be good or bad, depending on your skill and your desire. You might want that added feedback that steel shafts offer - or you might be tired of your hands stinging so much on mis-hit shots. The biggest and by far most important difference between steel and graphite shafts is this: graphite shafts are lighter than steel shafts. So clubs that have graphite shafts will be lighter than otherwise identical clubs that have steel shafts. The difference in weight between graphite shafts and steel shafts will translate, for most golfers, into an additional 2-4 mph of swing speed with graphite. And that could mean an extra 6-12 yards of distance with a graphite shaft, compared to a steel shaft. Steel shafts are less expensive than graphite, so the same set of clubs will cost less with steel shafts than with graphite shafts. Steel shafts were once considered much more durable than graphite. That's not s


What is the world's largest open mine?

The world's largest open-pit mine is the Bingham Canyon Mine in Utah, USA. It is also commonly known as the Kennecott Copper Mine. It is more than 0.75 miles deep and 2.5 miles wide, making it one of the largest man-made excavations in the world.

Why LM6000 PC using two shafts?

The compression ratio for LM6000 PC is quite high (30:1 usually) compared to a conventional Gas turbine, for achieving this high ratio the compressor design with two shafts is more efficient than a single shaft. So basically the efficiency of compression increases if you increase the no.of shafts, ie 3 shaft will be more efficient than 2 shafts. But the cost also increases with the no.of shafts involved. So finally if you see the trade off 2 shaft model works out to be the best. Ralini Pradeep Adatrao
