Question 1 (34 Marks)
The concurrent forces act at Point O shown in Figure (1).
1) Determine the magnitude of the Resultant force.
2) Determine the direction of the resultant force , measured counterclockwise from the
positive X-axis.
Question 2 (33 Marks)
Determine the magnitude of the resultant R of the two forces and the angle 0 which R makes
with the positive x-axis as shown in Figure (2).
Question 3 (33 Marks)
At what angle must the 1200 KN force be applied in order that the resultant R of the two
forces have a magnitude of 2000 KN? For this condition, determine the angle B between R
and the vertical.Figure (3)
