Problem $03\mathrm{.}085-$ A force applied to a bar to move a rock

A worker tries to move a rock by applying a $404-N$ force $P$ to a steel bar as shown.

Problem $03\mathrm{.}085-$ A force applied to a bar to move a rock

A worker tries to move a rock by applying a $404-$N force $P$ to a steel bar as shown.

Problem $03\mathrm{.}085.$b $-$ Replacement of a single force by an equivalent force$-$couple system

Two workers attempt to move the same rock by applying a vertical force at A and another force at $D.$ Determine these two forces if

they are to be equivalent to the force$-$couple system at $D.$

The two forces, $F_A=$

$N!$ and $F_D=$

$N$

: are equivalent to the force$-$couple system obtained in part
