Construct the interaction diagram relating P, to M, for the building column shown in Fig. P8.7. Bending will be about the axis a-a. Calculate specific coordinates for concentric loading (e = 0), for P, and at least three other points, well chosen, on the curve. Material strengths are f f, = 60,000 psi. |3| 8000 psi and a 20" a 3" 8" 8" 8" 3" 30" Ast 10 No. 14 (No. 43) %3D

The allowable shear stress is τallow=895 psi�allow=895 psi. The supports at A� and B� are smooth

A wooden frame shown below is supported by a tie rod CF and a pin support at A. The diameter of the tie rod CF is 30 mm, and the cross-sectional area of member BD is 900 mm?. The diameters of the pins at A and D are 8 mm and 12 mm, respectively, and each pin is subjected to double shear. If the weight of the bucket hanging from end E is 3 kN, determine (a) The axial stresses in tie rod CF and member BD. (b) The shear stresses in pins A and D. - 0.6 m-0.6 m→ D E 0.6 m V30B 1.2 m F

A square bar carries a series of loads as shown in Figure P1-47. Compute the stress in each segment of the bar. All loads act along the central axis of 1-47. the bar.
