An acrobat is walking on a tightrope of length L
=20.1 m attached to supports A and B at a
distance of 20.0 m apart. The combined weight
of the acrobat and his balancing pole is 900 N,
and the friction between his shoes and the rope
is large enough to prevent him from slipping.
Neglecting the weight of the rope and any
elastic deformation, determine the deflection (y)
and the tension in portion AC and BC of the
rope for values of x from 0.5 m to 10 m using
0.5 m increments.
1. Determine the maximum deflection (y) in
the rope.
2. Plot tension of AC and BC vs. x (on the
same plot with x on the x-axis). Turn in the
plot and the table of x, TAC, and TBC (clearly
label each).

A block hangs from the end of bar AB that is 5.80 meters
long and connected to the wall in the xz plane. The bar is
supported at end A by a ball joint such that it carries only a
compressive force along its axis. The bar is supported in
equilibrium at end B by cables BD and BC that connect to
the xz plane at points C and D respectively with
coordinates given in the figure. The z components of the
moments exerted on the bar by these two cables sum to 0.
The tension in cable BD is measured to be 210 Newtons.
Input answers of zero as 0.00 to avoid an invalid answer due
to significant figures.
Determine the equivalent force and couple system acting at
A that models only the forces exerted by both cables BD
