QUESTION 1
Fig. 1. shows a system of forces $F_1$, $F_2$ and $F_3$ in 3D acting on an idealized particle.
a) Determine the x, y and z scalar components of the resultant force F.
b) Express the Resultant Force F in cartesian vector form and determine the direction angles ($\alpha$, $\beta$, $\gamma$)
c) Determine the magnitude of the rectangular component of $F_2$ along the line of action of $F_1$
d) The angle between $F_1$ and $F_2$
QUESTION 2
For Fig. 2. shows a support system for a wooden balcony, knowing that the tension is 425 lb. in cable AB
and 710 lb. in cable AC, determine the magnitude and direction of the resultant of the forces exerted at A
by the two cables.
