What else can I help you with?
If a curve with a radius of 60 m is properly banked for a car traveling 60 kmh what must be the coefficient of static friction for a car not to skid when travelling at 90 kmh?
To prevent skidding at 90 km/h, the car would need a coefficient of static friction of at least 0.25. This value can be calculated using the formula: coefficient of friction = tan(theta), where theta is the angle of banking. Given the curve radius, speed, and the formula, we can determine the necessary value for the coefficient of friction.
How does friction effects peed on a skateboard?
I hope you mean speed, if not I'm at a loss for words. Friction effects both the contact between the wheels and the ground, as well as your shoe and the grip tape. You would like a high coefficient of static friction between the ground and your wheels so you don't end up skidding, fishtailing, and later flat-out falling down. Also, you would want a medium-level coefficient of kinetic friction and possible a medium-high coefficient of static friction between the grip tape and your shoe in order to grip the board, yet still be able to slide your foot for flip tricks. If the coefficient of static friction between the grip tape and your board is too high, it won't flip properly as it might overflip or flip on an unusual axis if it were to be too low. As you use the grip tape, both coefficients will decrease because the grains on the grip tape will be smaller and easier to pass over with a lesser repelling force of friction.

Which simple machine depends on friction to function properly?
The screw is a simple machine that depends on friction to function properly. When a screw is turned, the threads create friction with the material it is being inserted into, allowing it to hold objects together or lift loads.
Does a pulley use friction?
No, a pulley does not use friction. Pulleys are simple machines that use a wheel and axle to redirect the force applied to them. Friction is not necessary for a pulley to work properly.
How do you reduce friction on the shoes?
You can reduce friction on shoes by using products like lubricants or powders specifically designed for that purpose. Additionally, making sure your shoes fit properly and are not too tight can help reduce friction. Properly breaking in new shoes can also contribute to reducing friction over time.

Why do you need friction on animals?
Because without the friction on animals the the neutrons of the atoms would not be able to work properly.
What properly is important for glassware that use heated?
Very low CTE - coefficient of thermal expansion.
How does properly maintaining your bicycle increase its mechanical efficiency?
If it wasn't properly lubed before, then efficieny will be improved by lubricating. If it was properly lubed before, nothing much will happen.
Does friction affects motion?
Yes.Yes.Yes.Yes.

Can you write a sentence with the word measure in it?
One must measure the coefficient of disparity in a demand supply curve properly.
How can youu reduce the friction of the axles rotating in the chassis?
You can reduce friction by ensuring the axles are properly lubricated with a low-friction lubricant, such as graphite or silicone-based oils. Additionally, make sure the axles are aligned properly and that there is minimal contact between the axle and the chassis. Lastly, consider using polished axles or adding wheel bearings to reduce friction further.
