摘要:

A box of massm1rests on a rough plane elevated through an angle φ. The box is connected to a counterweight of massm2by an inextensible rope which passes over an ideal pulley at the higher end of the plane. The box may stick only if μs2≥M2−1, where μsis the coefficient of friction andM≡m2/m1. If, in addition, μs
