Sep 27, 2013 · 4.80 Two blocks M1 and M2 are connected by a mass-less string that passes over a massless pulley (Figure 4.46). M2, which has a mass of 20 kg, rests on a long ramp of angle θ equal to 30°. Friction can be ignored in this problem. (a) Find the value of M1 for which the two blocks are in equilibrium (no acceleration).
Since F is the only net force acting on the two masses, it determines the acceleration of both: The force F 2 acting on the smaller mass may now be determined. Note that by Newton's third law, the force F 2 acts backward on m 1. Note that the net force acting on m 1 is consistent with the above.
