A pin-ended chord of a truss is treated as a member in a braced frame. Its length is 12 ft. It must carry a tension dead load of 95 kips and live load of 180 kips along with a uniformly distributed transverse dead load of 1.2 kips/ft and live load of 2.3 kips/ft. Will a W8x67, A992 member be adequate if the transverse load is applied to put the bending about the strong axis? Determine by (a) LRFD and (b) ASD. [8.14- 12-Tension]

Given a 2x6 select structural DF-L top truss chord member loaded axially with 2800 lbs (dead plus live), determine if the given section is adequate. The chord is 8-ft long and is laterally braced at mid-length about the weak axis. Assume the ends are pinned and that the moisture content exceeds 19%.
A simple pin-connected truss is loaded and supported as shown in the figure.
A simple pin-connected truss is loaded and supported as shown in the figure. The load P is 200 kN. All members of the truss are aluminum pipes that have an outside diameter of 115 mm and a wall thickness of 6 mm. Determine the normal stress in each truss member. Assume truss dimensions of a = 12.0 m, b = 7.5 m, and c = 6.0 m.
Determine the force in each member of the truss supporting a floor deck
Determine the force in each member of the truss supporting a floor deck as shown in Fig. P4.28. The deck is simply supported on floor beams which, in turn, are connected to the joints of the truss. Thus, the uniformly distributed loading on the deck is transmitted by the floor beams as concentrated loads to the top joints of the truss.

 C++ Program Assignment The purpose of this program is to identify the forces of each member of the truss below (FAB, FAD, FBC, FBD, FBE, FCE, FDE) and to state whether they are in tension or compression. Use the example we worked in class to determine the reaction forces (Ax, Ay, and Cy) and complete the analysis by the Method of Joints. When you have finished the program, you will upload the .cpp file to D2L in the Assessment Dropbox folder...

a member in a braced frame supports an axial compressive load and end moments that cause bending about both axes of member. A second order analysis was performed with factored loads and and reduced members stiffnesses to obtain the moments and axial forces. USE LRFD and selet the lightest W shape of A992 steel? Axial=140 k. Mux= 150 ft-kips. Muy=150 ft-kips. Mux=75 ft-kips. Muy=75 ft-kips.

Nicole who is a one-member LLC. It says she has the option to be treated for tax purposes as a C corporation and also make the election to become an S corporation.I understand there might a tax benefit or disadvantage by electing to be treated as a C corp but why would a one-member LLC want to be treated as a S corp when they are both pass-throw entities and would have the same tax effect?
