1. The problem statement, all variables and given/known data A particle is placed on a rough plane inclined at an angle theta, where tan θ = μ = coefficient of friction(both static an dynamic). A string attached to the particle passes through a small hole in the plane. The string is pulled so slowly that you may consider the particle to be in static equilibrium at all times. Find the path of the particle on the inclined plane. 2. Relevant equations In equilibrium, by lami's theorem, A/sina = B/sinb = C/sinC 3. The attempt at a solution I have applied lami's theorem, taking three concurrent forces as mgsintheta, friction f and tension T, but am not getting any idea how to proceed to find the trajectory.
