1. Calculate the deflections, reaction forces and stresses for the truss shown in the figure (E=200GPa, A=3250mm2) using LISA FEA software.
2.Calculate the stresses and displacements in bicycle frame made of aluminum (Youngs modulus=70MPa and Poissons ratio = 0.33) and dimensions shown in figure below. Pipe outer diameter is 25mm and thickness is 2mm.
3.
