Tutorial Assignment 3 (100 marks, weighted 10%) Question 2: FEA on Dynamic Analysis and Vibration (50 marks) Assume the bar has a length of (1 + 0.q) m, a modulus of elasticity E of 70 GPa, a mass density p of 2700 kg/m². It has a square cross-section of (50 +q) x (50+q) mm as shown in the figure below. 1000 + q mm (50 + q) mm You are required to: a) determine the first two natural frequencies for the bar by using a theoretical procedure with 2-node bar elements (20 marks); b) determine the first five natural frequencies and mode shapes for the bar by using ANSYS WB (15 marks); and c) determine the first five buckling loads and mode shapes for the bar by using ANSYS WB (15 marks)
