Question: The forces and couple moments which are exerted on the toe and heel plates of a snow ski are Ft, Mt, and Fh, Mh, respectively.

The forces and couple moments which are exerted on the toe and heel plates of a snow ski are Ft, Mt, and Fh, Mh, respectively. Replace this system by an equivalent force and couple moment acting at point P. Express the results in Cartesian vector form.

Given:

a = 120 mm

b = 800 mm

Ft = (-50 80 -158) N

Mt = (-6 4 2) N ∙ m

Fh = (-20 60 -250) N

Mh = (-20 8 3) N. m

F, M b M, F,
