Step 1

1 of 2$\textbf{Given}$

$w = 120 \text{ lbs}$

$n = 600$

$\textbf{Approach}$

Average force per nail is calculated by dividing the weight with the number of nails or in other words:

$F_{nail} = \dfrac{w}{n}$

$\textbf{Solution}$

Inserting numerical values into the equation we get that the force per nail is equal to:

$F_{nail} = \dfrac{120}{600} = 0.2$ lbs
