PROBLEM 4.129 (Continued)
PROBLEM 4.130
Frame ABCD is supported by a ball-and-
socket joint at A and by three cables.
Knowing that the 350-N load is applied at
D (300 mm),a determine the tension in
each cable and the reaction at A.
PROBLEM 4.130 (Continued)
PROBLEM 4.131
The assembly shown consists of an 80-
mm rod AF that is welded to a cross
consisting of four 200-mm arms. The
assembly is supported by a ball-and-
socket joint at F and by three short links,
each of which forms an angle of 45 with
the vertical. For the loading shown,
determine (a) the tension in each link,
(b) the reaction at F.
PROBLEM 4.131 (Continued)
PROBLEM 4.132
The uniform 10-kg rod AB is supported by a ball-and-socket
joint at A and by the cord CG that is attached to the midpoint G
of the rod. Knowing that the rod leans against a frictionless
vertical wall at B, determine (a) the tension in the cord, (b) the
reactions at A and B.
PROBLEM 4.132 (Continued)
PROBLEM 4.133
The frame ACD is supported by ball-and-socket joints at A
and D and by a cable that passes through a ring at B and is
attached to hooks at G and H. Knowing that the frame
supports at Point C a load of magnitude P 268 N,
determine the tension in the cable.

PROBLEM 4.134
Solve Prob. 4.133, assuming that cable GBH is replaced by
a cable GB attached at G and B.
PROBLEM 4.133 The frame ACD is supported by ball-
and-socket joints at A and D and by a cable that passes
through a ring at B and is attached to hooks at G and H.
Knowing that the frame supports at Point C a load of
magnitude P 268 N, determine the tension in the cable.
