In the Figure, . Find Vector components for F1x, F2x,F2y,F2z,F3x,F3z. F1 =80 N, F2 =140 N, F3=200 N To find the components of force F1 use the small right angle triangle which is similar to the big shaded right angle triangle associated with F1: assume the angle between F1 and the y-axis is ?, then sin(?)=3/5cos(?)=4/5?tan(?)=3/4 which means the components for the force Vector F1=F1x+F1y+F1z where F1= Force Vector F1, F1 = the scalar value for F1 F1=F1(0)+F1(4/5)+F1(3/5)F1x=0 since no component for F1 in the X-direction. To find the components for force F3 use the small right anç 0 triangle which is similar to the big right angle shaded triang associated with F3: assume the angle between F3 and the X-Y-plane is ?, then Sin(?)=4/5Cos(?)=3/5?tan(?)=4/3 Since F3 is in the X?Y?Z plane, then resolve F3 into F3z and the projection of F3 in the X?Y plane in order to find F3x and F3y. Use the triangle in the x?y plane; F3x=F3(3/5),F3y=?F3(4/5) and F3z=F3(4/5) F3=F3x+F3y+F3z where F3= Force Vector F3, F3 = the scalar value for F3 F3=F3(3/5)+(?F3(4/5))+F3(4/5)
