PROBLEM 2.71
Determine (a) the x, y, and z components of the 600-N force, (b) the angles θx, θy, and θz that the force forms with the coordinate axes.
SOLUTION
(a) Fx = (600 N)sin 25°cos30 Fx =219.60N
Fy =(600N)cos25° Fy =543.78N
Fy 543.78 N cosθy = F = 600N
Fx =220N Fy =544N
Fz =126.8N (b) cosθx=x= θx=68.5°
Fz =(380.36N)sin25°sin30 Fz =126.785N
F 219.60 N F 600 N
F cosθz = z =
126.785 N 600 N
θy =25.0° θz =77.8°
