the are useful because they transmit a rotary motion they are used in shafts like the driveshaft in a car

Why does the water seep into the concrete walls of the house?
Answer: No fundamental difference
Explanation: There is no fundamental difference between nano-composite and conventional composites. Conventional composite have a particular structure similar like the nano- composite material which have a composition of the nano-crystals.They both have a hardness to some extent and also face damage under extensive load impact. Thus , they have certain difference but that can't be considered as the primary or fundamental.
Whipping is done in a forward direction. You deposit a dab or puddle of metal down, and then whip the rod forward and up a little to let that dab cool a bit, then you move back and deposit another dab slightly ahead of the previous dab.
Cellulose rod like 6010 and 6011 are known as "fast freeze" electrodes, also known to be deep penetrating rods. The "whip and stitch" motion is used so that you get the full benefit of the cellulose characteristics. The forward motion basically gouges out the base metal, and it gets filled in with the back-step.
Hope this helped:)
