PROBLEM 4.108 (Continued)
PROBLEM 4.109
Solve Problem 4.108, assuming that the 3.6-kN load is
applied at Point A.
PROBLEM 4.108
A 2.4-m boom is held by a ball-and-
socket joint at C and by two cables AD and AE. Determine
the tension in each cable and the reaction at C.

PROBLEM 4.110
The 10-ft flagpole AC forms an angle of 30 with the z axis. It
is held by a ball-and-socket joint at C and by two thin braces
BD and BE. Knowing that the distance BC is 3 ft, determine
the tension in each brace and the reaction at C.
PROBLEM 4.110 (Continued)
PROBLEM 4.111
A 48-in. boom is held by a ball-and-socket joint at C and by
two cables BF and DAE; cable DAE passes around a
frictionless pulley at A. For the loading shown, determine
the tension in each cable and the reaction at C.

PROBLEM 4.112
Solve Problem 4.111, assuming that the 320-lb load is
applied at A.
PROBLEM 4.111
A 48-in. boom is held by a ball-and-
socket joint at C and by two cables BF and DAE; cable
DAE passes around a frictionless pulley at A. For the
loading shown, determine the tension in each cable and the
reaction at C.

PROBLEM 4.113
A 10-kg storm window measuring 900 × 1500 mm is held by hinges at
A and B. In the position shown, it is held away from the side of the
house by a 600-mm stick CD. Assuming that the hinge at A does not
exert any axial thrust, determine the magnitude of the force exerted by
the stick and the components of the reactions at A and B.
