Friction on wedges

Decerto · 2008-06-14 17:15:31

Looking for some help with applied maths, when your given co-effecient of friction between wedge and ground, how do u go about calculating it. i know that you use R1= R+(mass_of_particle)gcos(angle) and Friction=(co-effecient)xR1, but in wedges your resultant(R) is given by the perpendicular F=ma of the particle, and in…
