PROBLEM 2.133
The end of the coaxial cable AE is attached to the pole AB,
which is strengthened by the guy wires AC and AD. Knowing
that the tension in wire AC is 120 lb, determine (a) the
components of the force exerted by this wire on the pole, (b)
the angles
θ
x,
θ
y, and
θ
z that the force forms with the
coordinate axes.
PROBLEM 2.134
Knowing that the tension in cable AC is 2130 N, determine
the components of the force exerted on the plate at C.
PROBLEM 2.135
Find the magnitude and direction of the resultant of the two forces
shown knowing that P = 600 N and Q = 450 N.
PROBLEM 2.136
A container of weight W is suspended from ring A.
Cable BAC passes through the ring and is attached to
fixed supports at B and C. Two forces
P=Pi
and
Q
Q=k
are applied to the ring to maintain the
container in the position shown. Knowing that W
376 N,=
determine P and Q. (Hint: The tension is
the same in both portions of cable BAC.)
PROBLEM 2.137
Collars A and B are connected by a 25-in.-long wire and can slide
freely on frictionless rods. If a 60-lb force Q is applied to collar
B as shown, determine (a) the tension in the wire when
9 in.,x=
(b) the corresponding magnitude of the force P
required to maintain the equilibrium of the system.
PROBLEM 2.138
Collars A and B are connected by a 25-in.-long wire and can slide
freely on frictionless rods. Determine the distances x and z for
which the equilibrium of the system is maintained when
120 lbP=
and
60 lb.Q=
PROBLEM 2F1
Two cables are tied together at C and loaded as shown.
Draw the free-body diagram needed to determine the
tension in AC and BC.
PROBLEM 2.F2
Two forces of magnitude TA = 8 kips and TB = 15 kips are
applied as shown to a welded connection. Knowing that the
connection is in equilibrium, draw the free-body diagram
needed to determine the magnitudes of the forces TC
and TD.
PROBLEM 2.F3
The 60-lb collar A can slide on a frictionless vertical rod and is connected
as shown to a 65-lb counterweight C. Draw the free-body diagram needed
to determine the value of h for which the system is in equilibrium.
