What would cause grinding noise gets louder at high speed?
wheel bearing
Why are sparks produced when a pair of scissors is sharpened against a grinding wheel?
Sparks are produced when a pair of scissors is sharpened against a grinding wheel due to the friction generated between the metal of the scissors and the abrasive surface of the grinding wheel. This friction generates heat, causing small particles of metal to oxidize and ignite, creating visible sparks. Additionally, the high speed at which the grinding wheel rotates contributes to the intensity of the sparks as metal shavings are ejected. The process is a combination of mechanical action and thermal energy release.
What is a grinding machines and how to use a grinding machine?
A grinding machine uses an abrasive wheel to final machine precision components to fine tolerances ,it is possible to achieve accuracy down to less than .001mm.There are 3 general types of grinding machine,Internal which machines bores,external which grinds outside diameters.and surface which grinds flat surfaces on components.There are other types of specialized grinding machine like gear/spline grinders etc . The grinding wheel rotates at high speed and is "dressed/trued up" by passing an industrial diamond over its surface. The wheel is then bought into contact with the work piece which will also be rotating when internal or external grinding or moving from left to right beneath the wheel when surface grinding.The work piece is now moved accross the face of the wheel to remove fine amounts of material until the required size is reached. Ther are many factors to take into account when grinding.ie type or grade of wheel used,rotational speed of wheel,speed of work piece,speed that wheel is moved/traversed accross workpiece.The way the wheel is dressed/trued up will affect how it cuts, and the surface finish achieved.
What is creep feed?
Creepfeed grinding is a grinding process that can, in most cases, be used as an alternative to reciprocating surface grinding. The main difference is: Reciprocating grinding - the machine table speed is fast (800-1600"/min), and the grinding wheel infeed amount is very small (0.0002-0.002"/pass). ie removing small amounts of material while the table moves quickly back and forth. Creepfeed grinding-the machine table speed is slow (2-50"/min), and the grinding wheel infeed amount is high (up to .25"/pass). ie removing a large amount of material in one (or a few) slow pass. Creepfeed grinders generally require: high rigidity, full machine enclosure, high horsepower spindle drive, high volume/pressure coolant
What happens when a starter motor rotates at a high speed?
it burns

What would cause a grinding sound coming from the front driver wheel when the car is driving straight and turning but stops when you get to a high speed?
lower ball joints need lubed up or probably replaced.
What are the parts of the grindstone?
A grindstone typically consists of three main parts: the grinding wheel, the housing or frame, and the motor. The grinding wheel is the abrasive surface that sharpens or shapes materials, often made of stone or composite materials. The housing supports the wheel and motor, providing stability and safety during operation. The motor drives the wheel, enabling it to rotate at high speeds for effective grinding.
Why a car vibrate at high speed and its steering wheel shake when braking just at high speed?
High speed vibration is often an indication of a wheel that is out of balance or a bent rim. It can also be a bent driveshaft or bad U-joint. Vibration when you brake at high speed is almost always a warped rotor on the disk brakes.
What would cause a grinding noise coming from my front drivers wheel when you go slow and turn but doesnt happen when you reach a high speed?
Without more detail, my first guess would be that you have worn down your break pad to the metal on the side that is grinding. What your hearing is the metal from the pad grinding on the rotor. If this is the case then you may hear it get worse when you apply pressure to the breaks. You will want to replace the pads on "both" sides of the car and you might need to replace the rotor or have the rotor turned that is on the grinding sound side ASAP.
Why do Honda Accord steering wheel shake at low speed and not at high speed?
It could be a shifted belt in one of the tires.
What is the rattle in a car when the gear stick is wobbled fom side to side while in neutral and the engine is off?
It is the sound of the gears grinding against each other. Because it is at a high speed, it sounds like a rattling instead of a grinding.
