Best ResponseYou've already chosen the best response.0so:in direction of normal to incline:\[NFsin \theta =mgcos \theta\]& in direction of down of incline:\[mgsin \thetaFcos \theta\mu _{s}.N=ma=0\]so if you solve 2 equation for mu yields:\[(Fcos \theta+mgsin \theta)/(Fsin \theta+mgcos \theta)=\mu _{s}\]

Best ResponseYou've already chosen the best response.0dw:1333455525796:dw dw:1333455661277:dw where Ff is frictional force sum up all these forces acting on the body i have shown different diagrams to avoid confusion i want the body to be in rest so all those vertical forces (on bothe sides of incline) and horizonatal forces(acting on both sides shud be equal)
