A three bar space truss is subjected to a load applied through a cable going over an ideal
pulley and attached to a weight. The coordinates of the pulley (in feet) are (24, -20, 0).
Members 1 and 2 are in the horizontal plane and paralle
1. Looking at a simply supported beam with an axial load and a point load, find the
maximum displacements using both first order and second order analysis.
tan(L/2)*(-w/2P) + wL/4P

Use SAP to determine the maximum displacement and maximum moment of this beam,
which has a traverse load, applied at the center of the beam and an axial load applied at
the end. Use W=2lb, P=0.5*Pcr, E=10e6 psi, L=36in 1in x 3/8in sectio
1) Determine the location of the centroid and shear center for the section shown using the
standard thin-walled approximation.
X_bar = 162.5mm
Y_bar = 260mm
e = -84.4mm
2) Use the cross section give with a concentrated load of 8kN to cal
