Question 1
(a) The plate is subjected to the two forces at A and B as shown in the Figure below. If θ= 45⁰, determine the magnitude of the resultant of these two forces and its direction measured clockwise from the horizontal.
(b) Determine the angle of for connecting member A to the plate so that the resultant force of FA and FB is directed horizontally to the right. Also, determine the magnitude of the resultant force.
Question 2
Determine the magnitude of the vertical force acting on the tower (along z-axis) due to the three cable forces FAB, FAC, and FAD using unit vector in Cartesian coordinate system.
