PROBLEM 4.135
The bent rod ABDE is supported by ball-and-socket joints
at A and E and by the cable DF. If a 60-lb load is applied
at C as shown, determine the tension in the cable.
PROBLEM 4.136
Solve Problem 4.135, assuming that cable DF is replaced
by a cable connecting B and F.

PROBLEM 4.137
Two rectangular plates are welded together to form the
assembly shown. The assembly is supported by ball-and-
socket joints at B and D and by a ball on a horizontal
surface at C. For the loading shown, determine the reaction
at C.
PROBLEM 4.138
The pipe ACDE is supported by ball-and-socket joints at A and E
and by the wire DF. Determine the tension in the wire when a
640-N load is applied at B as shown.

socket joints at A and E and by the wire DF. Determine the
tension in the wire when a 640-N load is applied at B as shown.
PROBLEM 4.140
Two
24-ft
plywood panels, each of weight 12 lb, are nailed
together as shown. The panels are supported by ball-and-
socket joints at A and F and by the wire BH. Determine
(a) the location of H in the xy plane if the tension in the wire
is to be minimum, (b) the corresponding minimum tension.

PROBLEM 4.141
Solve Problem 4.140, subject to the restriction that H must lie
on the y-axis.
