## Main Question or Discussion Point

I have two surfaces that have a coifficent of friction of .6. Disregarding mass (if possible) at what angle would the force of static friction and the normal force be equal

Not possible. The normal force depends on the mass. Since the frictional force is equal to the coefficient of friction times the normal force they can never be equal unless the coefficient of friction is one and that would be true of any angle.Disregarding mass (if possible) at what angle would the force of static friction and the normal force be equal

And what would that be in the case of a slide at an angle Θ?

G is acceleration of gravity

° is the angle of the steel slide

N is normal force applied to object

according to that if the slide is at 0 deg then the normal force is 0? Is that OK with you?

I was questioning your formula for the normal force.

MgsinΘ is not the normal force so what is the normal force?

Ff=un

Ff is frictional force

U is the coifficent of friction

N is normal force

Ff is frictional force

U is the coifficent of friction

N is normal force

Wouldn't the normal force be N=mgcos°

So mgsin°=umgcos° would be the equation I would have to evaluate and isolate °?
