PROBLEM 7.116
Cable ACB supports a load uniformly distributed along the
horizontal as shown. The lowest Point C is located 9 m to the
right of A. Determine (a) the vertical distance a, (b) the length
of the cable, (c) the components of the reaction at A.

PROBLEM 7.117
Each cable of the side spans of the Golden Gate Bridge
supports a load w= 10.2 kips/ft along the horizontal.
Knowing that for the side spans the maximum vertical
distance h from each cable to the chord AB is 30 ft and
occurs at midspan, determine (a) the maximum tension in
each cable, (b) the slope at B.

PROBLEM 7.118
A steam pipe weighting 45 lb/ft that passes between two
buildings 40 ft apart is supported by a system of cables as
shown. Assuming that the weight of the cable system is
equivalent to a uniformly distributed loading of 5 lb/ft,
determine (a) the location of the lowest Point C of the
cable, (b) the maximum tension in the cable.

PROBLEM 7.119*
A cable AB of span L and a simple beam ABof the same span are
subjected to identical vertical loadings as shown. Show that the
magnitude of the bending moment at a point C in the beam is equal
to the product T0h, where T0 is the magnitude of the horizontal
component of the tension force in the cable and h is the vertical
distance between Point C and the chord joining the points of support
A and B.
