Homework Help: What could you do to increase efficiency?

  1. Jan 2, 2010 #1
    1. The problem statement, all variables and given/known data

    What could you do to increase efficiency between the cart and the ramp? As in pulling a cart (with wheels) up an inclined plane.

    2. Relevant equations

    3. The attempt at a solution

    One solution could be increasing the angle to increase efficiency. I was wondering if increasing/decreasing mass or increasing/decreasing the coefficient of friction would increase efficiency? Anything else?

    You could formulate an equation for the work output and see what it depends on. But yes, decreasing the coefficient of friction would decrease friction and hence the work done against friction would decrease.
