## Homework Statement

Determine the resultant of the system and the x- and y- intercepts of its line of action. Not that the front and rear tracks are equal (i.e., AB = CD)

## The Attempt at a Solution

Frx = 300 N + 300 N + 150 N*(cos30deg) + 200 N*(cos30deg) = 903.19 N

Fry = 0 + ) + 150 N*(sin30deg) +200 N*(sin30deg) = 175 N

Fr = 903.109

**i**+ 175

**j**

||Fr|| = 919.908

angle = arctan( Fry/Frx ) = 175/903.109 N = 10.067 degrees

M FO = 760 mm*(300 N) - 760 mm*(300 N) + 1120mm*(150sin(30)) + 760 mm*(150cos(30)) - 760*(200cos(30)) + 1120 mm(sin(30)) = 51651.035 N*mm

FFrd = MO

919.909 N*d = 515651.035 N*mm

d = 56.148

I'm not sure how to find the x- and y- intercepts...can anyone lead me in the right direction please? thanks!
