The coefficient of static friction is defined at the critical/Maximum inclination angle at which the block "begins" to slide. Hence, for a vehicle on an inclined plane at this critical angle, the braking force at this critical angle is given by:
i.e [tex]F_{braking}=\mu_{static} N[/tex] at [itex]\theta _{max}[/itex]
For anything beyond[itex]i.e >\theta_{max}[/itex] the braking force is given as
[tex]F_{braking}=\mu_{dynamic} N[/tex]
Obviously,at any angle below the critical angle, the vehicle "park brakes" need not be applied because the vehicle will not move.
My question: Will the "park brakes" need to be applied AT the critical angle or BEYOND the critical angle?
Assumption:
Both the front and rear tires are on a the road with same coefficients of friction.
