  1. Probably F * 49.6 = 1460 * 1.90

    but I do not see a figure

  2. In the nail puller shown in the figure below you exert a force 53.2 cm from the pivot and the nail is 1.50 cm on the other side. What minimum force must you exert to apply a force of 1380 N to the nail to pull the nail up?
    =
    38.9 N

    What is the mechanical advantage of the nail puller?
    =
    35.5

    how do you get the answers, what are the steps?
