1. Model the truss below in SAP2000. Give all members a cross-sectional area of 2.0 in-and i = 35 in*. Use the steel material (E = 29,000 ksi). Find all of the bar forces and report them in a table. Now change the cross-sectional area of all bars to A 3.0 in2. What change, if any, occurs in the bar forces of this statically determinate truss? 30 k 60k C 60 kT 20 k 18 ft 18 ft

2. Model the truss provided below in SAP2000. Give all members a cross-sectional area of 2.0 in2 and i = 35 in*. Use the steel material (E 29,000 ksi). Find all of the bar forces and report them in a table. Now remove all point loads and then apply a downward vertical point load of 110 k at point E. Find all bar forces. Does this loading scenario produce any peculiar behavior in the truss? 20 k 10k E 20...

5. (20 points) The truss shown below supports horizontal forces of 6 kips at Joint G, 8 kips at Joint E, and 4 kips at Joint C. All truss members are made of steel (E 29,000 ksi). Each of the diagonal members (Members AD, DE, and EH) has a cross-sectional area of 1.2 in2. Each of the vertical members (Members AC, CE, EG, BD, DF and FH) has a cross-sectional area of 2.4 in Each of the horizontal members (Members...

Problem 3: Use the method of virtual work and determine the vertical displacement of joint B of the truss. Point C is roller support and point A is pin support. Each steel member has a cross- sectional area A 0.465 in.2E-29000 ksi. (Hint: you may just do the structural analysis once and do the proportion for the internal force).

The truss is to be analyzed assuming the two loads shown are each 80 kips. By analyzed I mean that reactions at supports are to be determined and the forces (magnitude and sense) acting internally in each member are to be determined. Once forces are known, the members are to be "designed" -that is, the cross sectional area required determined-based on the following...
