The horizontal beam ABC shown in the figure is supported by columns BD and CE. The beam is prevented from moving horizontally by the pin support at end A. Each column is pinned at its upper end to the beam, but at the lower ends, support D is a sliding support and support E is pinned. Both co lu in us arc solid steel bars (E = 30 × 106 psi) of square cross section with width equal to 0.625 in. A load Q acts at distance a from column BD. If the distance a = 12 in., what is the critical value Qcr of the load? If the distance a can be varied between 0 and 40 in., what is the maximum possible value of Qcr? What is the corresponding value of the distance a?
Segments AB and BCD of beam ABCD are pin connected at x = 10 ft. The beam is supported by a pin support at A and roller supports at C and D; the roller at D is rotated by 30* from the x axis (see figure). A trapezoidal distributed load on BC varies in intensity from 5 lb/ft at B to 2.5 lb/ft at C. A concentrated moment is applied at joint A, and a 40-lb inclined load is applied at the mid-span or CD.

The roof beams of a warehouse are supported by pipe columns (see figure) having an outer diameter d2= 100 mm and inner diameter d2, = 90mm. The columns have a length L = 4.0 m, modulus E = 210 GPa, and fixed supports at the base. Calculate the critical load Pcrof one of the columns using the following assumptions: (a) the upper end is pinned and the beam prevents horizontal displacement; (b) the upper end is fixed against rotation and the beam prevents horizontal displacement; (c) the upper end is pinned, but the beam is free to move horizontally; and (d) the upper end is fixed against rotation, but the beam is free to move horizontally.
An overhanging beam ABC has a guided support at A, a rectangular cross section, and supports an upward uniform load q = PtL over AB and a downward concentrated load P at the free end C {see figure). The span length from A to B is L, and the length of the overhang is L12. The cross section has a width of A and a height A. Point D is located midway between the supports at a distance d from the top face of the beam. Knowing that the maximum tensile stress (principal stress) at point Z> is tr, = 38 MPa, determine the magnitude of the load P. Data for the beam are L = 1.75 m, b = 50 mm, // = 220 mm, and d = 55 mm.

Repeat part (a), but assume a pin support at A. Find an expression for the critical moment Mcr(i.e., find the moment M at B at which the system collapses because of Euler buckling of the columns).

The cantilever beam AB shown in the figure is an S6 × 12.5 steel I-beam with E = 30 × 106 psi. The simple beam DE is a wood beam 4 in. x 12 in. (nominal dimensions) in cross section with E = 1.5 x 106 psi. A steel rod AC of diameter 0.25 in., length 10 ft, and E = 30 x 106 psi serves as a hanger joining the two beams. The hanger fits snugly between the beams before the uniform load is applied to beam DE. Determine the tensile force Fin the hanger and the maximum bending moments MABand MDEin the two beams due to the uniform load, which has an intensity q = 400 lb/ft.
