The forces and couple moments exerted on the toe and heel plates of a snow ski are F, = {-50i +80j158k} N, M, = {-6i+4j + 2k} N. m, and F = {-20i+60j - 250k} N, M = {-20i+8j+ 3k} Nm, respectively. Replace this system by an equivalent force and couple moment acting at point O. Express the results in Cartesian vector form. Problems 4-124/125 F₁ Fh M₁ 120 mm M 800 mm
