First time posting here. . .
Okay, usually I'm pretty good figuring these type of questions out, but the textbook just doesn't help(no e.g.'s or explanations) and the teacher didn't talk at all about static friction, so, if anyone could give me a hand, I'd be very grateful.
Question:

What are factors that effect static friction?
I know that mass has an effect and the surface area has no effect, but what are others that have an effect on static friction and that you would think have an effect even though they dont?
A box of mass 32.0 kg sits on a horizontal steel ramp 3.4 m long with a coefficient of static friction of 0.30 between the ramp and the box. The end of the ramp is slowly lifted until the box begins to slide down the ramp. What angle does the ramp make with the ground when this happens?
What...
Alright folks i have a rather simple problem. I trying to figure this problem out: A small box of mass m_1 is sitting on a board of mass m_2 and length L . The board rests on a frictionless horizontal surface. The coefficient of static friction between the board and the box is mu_s . The...
a drag car's tires have some of the highest friction coefficients, so the book says.
it takes 6 s to go a quarter mile (about 402.5m) with constant acceleration, no skidding
what is the coefficient for the static friction?
A CORRECTION HAS BEEN MADE, IT IS 402.5m NOT 602.5
