PROBLEM 3: Consider the following cable system: cables AE, BE, CE, and DE intersect at point E. The coordinates of A, B, C and E are given: A (-2, 3, 2) m B (0, -2,5) m C (-3, 3, -1) m E (4, Y, 1) m Projection angles of D are 0 = 24°, and a = 10°, and distance L = 6 m. The length of cable AE is 4.8 m. Note the at D is on plane x-z. The forces in each cable are: EA = 122 KN EB = 111 KN EC = 95 KN ED = 108 KN

PROBLEM 3: Consider the following cable system: cables AE, BE, CE, and DE intersect at point E. The coordinates of A, B, C and E are given:
A (-2, 3, 2) m
B (0, -2,5) m
C (-3, 3, -1) m
E (4, Y, 1) m
Projection angles of D are 0 = 24°, and a = 10⁰, and distance L = 6 m. The length of cable AE is 4.8 m. Note the at D is on plane x-z.
The forces in each cable are:
EA = 122 KN
EB = 111 KN
EC = 95 KN
ED = 108 KN
