5. Two steel channels are used as a column which is 35 feet long. The channels are back to back with a 6" spacing. The column is pin connected at its ends in both directions. Determine the buckling load if a) they are not connected together b) they are latticed together as shown. A plate connects the channels together at the top and bottom for each case.

Step 1
The buckling load can be calculated using Euler's formula: Pcr = π²EI / (KL)² where: Pcr = critical load (buckling load) E = modulus of elasticity I = moment of inertia K = effective length factor (1.0 for pin-pin connection) L = length of the column The moment Show more…

The beam supports the load of $P=6$ kip.As a result. the $\mathrm{A} 992$ steel member $B C$ is subjected to a compressive load. Due to the forked ends on the member, consider the supports at $B$ and $C$ to act as pins for $x-x$ axis buckling and as fixed supports for $y-y$ axis buckling. Determine the factor of safety with respect to buckling about each of these axes.
Four wooden members are joined with metal plate connectors and are in static equilibrium (not moving) under the action of the four forces shown. If FA = 2.3 kN and FB = 2.1 kN, determine the magnitudes of FC and FD. Two cables are tied together at C and are loaded as shown.
