    Answer:

    1. Laod = 500 N

    2. Effort = 250 N

    Explanation:

    From the question given above, the following data were obtained:

    Input work = 187.5 J

    Output work = 125 J

    Load distance = 25 cm

    Effort distance = 75 cm

    1. Determination of the load.

    Output work = 125 J

    Load distance = 25 cm = 25/100 = 0.25 m

    Load =?

    Output work = Load × Load distance

    125 = Load × 0.25

    Divide both side by 0.25

    Load = 125 / 0.25

    Laod = 500 N

    2. Determination of the effort.

    Input work = 187.5 J

    Effort distance = 75 cm = 75/100 = 0.75 m

    Effort =?

    Input work = Effort × Effort distance

    187.5 = Effort × 0.75

    Divide both side by 0.75

    Effort = 187.5 / 0.75

    Effort = 250 N
