A load P is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 12600 ksi] rods, and a solid steel [E = 32100 ksi] rod, as shown. The bronze rods (1) each have a diameter of 0.61 in. and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 0.42 in. Assume L₁-53 in and L₂=73 in. If all bars are unstressed before the load P is applied, determine the normal stresses in bronze rods (1) and steel rod (2) after a load of P = 21 kips is applied. Answers: 0₁ = i 02 = i L₂ (2) B ksi. ksi.
How we draw the freebody Diagram for B ( and how we relove it with angle 60 dgree ) ???
Design a wide flange W column 8 m in height to support an axial dead load of 1000 kN and a live load of 1200kN in the interior of a building. The column base is rigidly fixed to the footing and the top of the column isrigidly framed to very stiff girders. Assume that bracing is provided to prevent side sway in the weak axis/planeof the column (you don’t have to consider slenderness in this direction), but side sway is not prevented aroundits strong axis. Select an economical W shape.
A load P is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 15800 ksi] rods, and a solid steel [E = 27600 ksi] rod, as shown. The bronze rods (1) each have a diameter of 0.62 in. and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 0.41 in. Assume L₁=30 in and L₂-62 in. If all bars are unstressed before the load P is applied, determine the normal stresses in bronze rods (1) and steel rod (2) after a load of P=32 kips is applied.

I neeed typing clear
Figure 2 shows an assembly made of a steel tube of internal and external diameter of 20 mm and 30 mm respectively, brass and copper bars, each having 25 mm of diameter. The three materials have equal length of 500 mm and are symmetrically rigidly fixed at the upper end while being joined by a horizontal collar (with negligible mass) at their bottom end. An application of a vertical downward load P on the assembly, results in storing a total of 20 J of energy. Brass Copper Steel Collar Figure 2: A system of steel tube, brass and copper bars The moduli of elasticity for steel, brass and copper materials are Es=200 GPa, EB=100 GPa and Ecu=80 GPa, respectively. Calculate: 2.1. The load P if it is applied gradually 2.2. The load P if it is applied suddenly 2.3. The impact load P that falls from a height of 200 mm above the collar.
Hi please help me answer this problem and draw free body diagram
A load P is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 14100 ksi] rods, and a solid steel [E = 28000 ksi] rod, as shown. The bronze rods (1) each have a diameter of 0.61 in. and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 0.47 in. Assume L₁-39 in and L2-72 in. If all bars are unstressed before the load P is applied, determine the normal stresses in bronze rods (1) and steel rod (2) after a load of P = 29 kips is applied.
