Question details

Question Consider the mechanism shown, pinned at points A, B and C, with a handle EA and a control rod BC which has a 25mm diameter uniform circular cross-section, a Yield stress of 250MPa and E-200GPa. 350 mm 250 mm 450 800 mm (i) Sketch the free body diagram EAB showing all external forces TS F [2 marks] (ii) Determine the axial load applied at the rod BC as a function of external force BC [5 marks] (iii) Determine the moment of inertia for the rod BCs cross-sectional area 1)m [2 marks]
5104MECH Applied Mechanics 2 (Static) (iv) What is the buckling effective length factor K for the rod BC Answer: K#1 1 mark] (v) Applying Eulers formula, determine the critical buckling load for the rod BC 5.13 (0) [5 marks (vi) Determine the maximum force P that can be applied to the handle EA so that the control rod BC does not buckle [5 marks] (vii) Determine the critical stress at the control rod BC Answer: 120.5MPa [3 marks (vii) Is the Eulers formula valid for this analysis? Why? e \20 2 marks]
