In the nail puller shown in the figure below you exert a force 49.6 cm from the pivot and the nail is 1.90 cm on the other side. What minimum force must you exert to apply a force of 1460 N to the nail to pull the nail up?

Answer 1

Probably F * 49.6 = 1460 * 1.90

but I do not see a figure

Answer 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?
