Question
All bars in the truss have the same cross section and material.
(1) The system must have a vertical displacement at point B
of less than 0.065 in, and a maximum absolute value of the
normal stress less than 24 ksi in all the bars. Based on these
two constraints, find the allowable load P.
(2) Assuming P = 8k, find the stress
at point p in the coordinate
system given.
