two blocks are connected by a string. the smooth incline surface makes an angle of 42 degrees with the horizontal, andthe block on the incline has a mass of 6.7 kg. find the mass of the hanging block that will cause the system to be in equilibrium. (the pully is assumed to be ideal.)

  • physics - ,

    Let mass of hanging block be M
    Since in equilibrium the hanging mass MG = Tension in the wire

    Similarly along the incline Tension in the wire = 6.7 * g * sin 42 (Component of force along the incline)

    So equation both the equations:

    M*g = 6.7 * g * sin(42)
    M = 6.7*sin(42)

    So M = 6.7*sin(42)
