(1) 63 N at 90°

(2) 40 N at 0°

(3) 83 N at 270°

(4) 40 N at 180°

(5) 50 N at 60°

What are the magnitude and direction of a sixth force that would produce equilibrium?

**Damon**, Saturday, December 15, 2012 at 5:21pmfind sum in x direction

63 cos 90 + 40 cos 0 + 83 cos 270 + 40 cos 180 + 50 cos 60

=50 cos 60 = 25 N at 0 deg

find sum in y direction

63 sin 90 + 40 sin 0 etc = 23.3

tan theta = 23.3/25 = .932

theta = 43

we want equal and opposite

so 43 + 180 = 223 degrees

magnitude = sqrt (625+543)

= 34.2 Newtons
