Q-1 Link-2, shown in the figure, is 30 mm wide, has 12 mm diameter bearings atthe ends, and is cut from low carbon steel bar having a minimum yield strength of190 MPa. The end-condition constants for link-2 are C = 1 and C = 1.2 for bucklingin and out of the drawing, respectively.a) Draw necessary and clear free-body diagrams to determine the reactions atthe supports and the load on both member-2 and member-3. b) Determine a suitable thickness for link-2, based on a design factor of safetyηD = 4, and considering a material having E = 207 GPa, and a minimum yieldstrength Sy = 350 MPa.c) Determine the stress and resulting factor of safety for each pin, and state yoursuggestions in case of design factors less than 4.
