Question summary: Solve the problem. A wooden block sitting at rest on a flat, level board will just begin to slide when the board is tilted up to a critical angle of inclination, θs . An experiment that determines this critical angle can be used to find the coefficient of static friction, μs , for the block on the board by using the relation Rewrite this relation using a quotient identity.: μs = tan2 θs; μs = cot θs; μs = tan θs; μs = sec θs
Right answer summary: μs = tan θs
