Using the formula $F _ { 1 } = M A \times F _ { 2 }$, we can solve for $F_2$ as follows:
$$F _ { 1 } = 6,160, \quad MA = 70, \quad F_2 = ?$$
$$F _ { 1 } = M A \times F _ { 2 } \rightarrow F _ { 2 } = \frac { F _ { 1 } } { M A } = \frac { 6,\!160 } { 70 } \approx 88 \text{ lb}$$
Therefore, the answer is B, 88 lb.

$F _ { 1 } = 6,160$ And $M A = \frac { 70 } { 1 }$
