## Question:

The forces and couple moments which are exerted on the toe and heel plates of a snow ski are ${ F }_{ t }$, ${ M }_{ t }$, and ${ F }_{ h }$, ${ F }_{ h }$, respectively. Replace this system by an equivalent force and couple moment acting at point $O$. Express the results in Cartesian vector form.

Given:

$a$ = $120$ $mm$

$b$ = $800$ $mm$
