Physics pulleys, mass equilibrium problem?
Two blocks are connected by a string. The smooth inclined surface makes an angle of = 37В° with the horizontal, and the block on the incline has a mass m1 = 6.3 kg. Find the mass m2 of the hanging block that will cause the system to be in equilibrium. The effective force on mass 1 (in the direction down the ramp) is its weight times the sine of 37 degrees.
Therefore the weight of the hanging block m2 should be the weight of the sliding block times the sine of 37 degrees.
