A solid, round beam AB (D = 200 mm) is to be machined from AISI 4140 [Q&T at T=425 C (800 F)] and will be used as mounting beam to overhang a newly developed jet engine inside the static test cell as illustrated in Figure 1 where the output thrust will be evaluated by a team of propulsion engineers. The beam is fully fixed to the building's wall structure and shall have an overall length of L = 4,500 mm. Over the course of testing programme, the beam is expected to be the primary load-bearing component and under that of worst-case scenario, to simultaneously take the three stress-inducing loads from the following operational conditions: 1. the engine accurate weight, acting via its centre of gravity (cg), ME= 7,339.45 kg. 2. the propulsive output thrust, Fr= 200,000 N and, 3. the simulated impact load from landing gear at touch down, FL = 115,000 N. By the resulting stress components from a combined loading system acting to the beam, devise: a) plot of shear force and bending moment diagram along the beam and, b) static design safety factor for the beam following that the stipulation of Tresca maximum shear stress criterion. 2200 1000 A -Cg 4500 Engine Mounting Beam F 1700 F [CO1, PO1, C41 B All length units in mm
