PROBLEM 4.124
Solve Problem 4.123, assuming that the 1.8-
kN load is applied at C.
PROBLEM 4.123 The rigid L-shaped
member ABC is supported by a ball-and-
socket joint at A and by three cables. If a 1.8-
kN load is applied at F, determine the
tension in each cable.
PROBLEM 4.125
The rigid L-shaped member ABF is supported by
a ball-and-socket joint at A and by three cables.
For the loading shown, determine the tension in
each cable and the reaction at A.
