    Answer:

    1) 1000Nm

    2)  95,625Nm

    3) 1.05%

    Explanation:

    Mechanical Advantage is the ratio of the load  to the effort applied to an object.

    MA = Load/Effort

    1) Workdone on the load = Force(Load) * distance covered by the load

    Workdone on the load = 500N * 2m

    Workdone on the load = 1000Nm

    2)  work done by the effort = Effort * distance moves d by effort

    work done by the effort = 2125 * 45

    work done by the effort = 95,625Nm

    3) Efficiency = Workdone on the load/ work done by the effort * 100

    Efficiency = 1000/95625 * 100

    Efficiency = 1.05%

    Hence the efficiency of the system is 1.05%
