µ is constant for all blocks, only masses are your variables EDIT: data for this task were symbols

You 're right tiny-tim. The blocks are stationary and question is about the limit of the masses of that blocks for which the system remains in balance. µ is given. Final equation should looks: mgsin(30°)+ µmgcos(30°)+µmg=2mg But this isn't standard task that we have to designate limits...

Homework Statement Last time I have had problem with one task: http://img543.imageshack.us/i/cosc.jpg/ They questioned us to determine compartments in with that configuration will be on balance. Informations: u-Friction alpha=30 Homework Equations If that configuration must be on...

Yes this points are laying on the graph y= f(x) "inside" means that this points are in the circle or outside below ,above the parabola.

Maybe this help There are possible answers: Finding pairs (x,y) are the co-ordinate points a) lyings below straight line y = -2x + 1; b) lyings inside the circle x^2 + (y -3)^2= 9 ; c) lyings outside the circle x^2 + (y - 3)^2 = 9; d) lyings below the parabola y = -2...

Find all the pairs (x, y)R^2, through which does not cross any curve : y = - x^2 + (4-2p)x + p^2 . Finding pairs (x,y) are the co-ordinate points . Thanks for help
