Homework Statement
Mass 1 of 1 kg is resting on an inclined plane of 30 degrees. A string is attaached to the mass and ran through a pulley at the top of the plane and attached to a suspended mass 2 of 2 kg. How far must the inclined plane be rotated until mass 1 starts to move down the incline.
Homework Equations
The Attempt at a Solution
So I am trying to use all of my knowledge of inclined planes to no avail. Firstly the force of friction must be the forced imposed upon mass1 by the gravitational force of mass 2 minus the gravitational force in the direction of the incline (m1*g*sintheta+Ffriction*g2*g)
