    Answer: Machanical advantage of the machine is 1.86

    Explanation: Machanical advantage of a machine is the ratio of the Force to overcome which is the load in this case 24kg * 10 = 240N to the force exerted (Effort) to overcome the load in this case 129N.

    So, we have

    MA = load/effort

    = 240N/129N

    = 1.86.
