The forces and couple moments that are exerted on the toe and heel plates of a snow ski are Ft, = {- 50i + 80j –158k} N, Mt = {-6i + 4j + 2k} N • m, and Fh, = {-20i + 60j –250k} N, Mh, = {-20i + 8j + 3k} N • m, respectively. Replace this system by an equivalent force and couple moment acting at point P. Express the results in Cartesian vector form.
