which two surfaces would have the highest coefficient of friction?
A. rubberon steel
B. wood on dry concrete
C. teflon on steel
D. rubber on dry concrete
I would say D on rubber on dry concret this is my opinoin my answer may be worthless but some one who knows is answering....
Friction is the static electricity of two things that are rubbed against each other. The highest coefitient of friction will be rubber and dry concrete. Because the highest coefitioent of friction is that the two surfaces in contact have a greater resistance.
So the answer would be
D. Rubber on dry concrete
Hope this helps ;P
