PROBLEM 4.119
Solve Prob. 4.113, assuming that the hinge at A has been removed and
that the hinge at B can exert couples about axes parallel to the x and y
axes.
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.

PROBLEM 4.120
Solve Prob. 4.115, assuming that the hinge at B has been removed
and that the hinge at A can exert an axial thrust, as well as couples
about axes parallel to the x and y axes.
PROBLEM 4.115 The horizontal platform ABCD weighs 60 lb
and supports a 240-lb load at its center. The platform is normally
held in position by hinges at A and B and by braces CE and DE. If
brace DE is removed, determine the reactions at the hinges and
the force exerted by the remaining brace CE. The hinge at A does
not exert any axial thrust.

PROBLEM 4.121
The assembly shown is used to control the tension T in a tape that
passes around a frictionless spool at E. Collar C is welded to rods
ABC and CDE. It can rotate about shaft FG but its motion along the
shaft is prevented by a washer S. For the loading shown, determine
(a) the tension T in the tape, (b) the reaction at C.

PROBLEM 4.122
The assembly shown is welded to collar A that fits on the
vertical pin shown. The pin can exert couples about the x
and z axes but does not prevent motion about or along the y-
axis. For the loading shown, determine the tension in each
cable and the reaction at A.

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.
