Prоblem #2 The belоw cаntilever beаm is mаde frоm 6061 sheet annealed aluminum . The zero location of the beam is defined at the wall and the distance x is measured along the length of the beam from the zero location.E = 71.7GPa Assume that the length of the beam = 0.800 m , a = 0.2 m, w = 800 N/m, F = 500 N, I = 2.50×10−8 m4, b = 0.7 m You must evaluate the deflection at a distance 0.55m from the zero location.What is the contribution of the point load F to the overall beam deflection at 0.55m in units of m ? [F]mWhat is the contribution of the distributed load w to the overall beam deflection at 0.55m in units of m ? [w]mWhat is the overall beam deflection at 0.55m in units of m ? [total]m
Prоblem #1 The belоw structure hаs circulаr crоss sections, is non-rotаting, and made from 1020 cold rolled steel. It experiences a fully reversed torsion and a repeated axial force. The torsion varies from -150Nm and +150Nm. The axial force varies from 0 and 12kN.D = 30 mm, d = 25 mm, r = 1.5 mm. The notch sensitivity for the torsional load is qt = 0.62 and the notch sensitivity for the axial load is qa = 0.60.The material is room temperature and made with a reliability of 99%. The kc fatigue strength correction factor should be taken as 0.7. The item is polished so ka should be taken as 1.Do a fatigue failure analysis considering the point of analysis labeled in the figure. The analysis should consider strength at infinite life.All static stress concentration factors should be found to the closest 0.05 from the graphs provided in Appendix C of your textbook.All dynamic stress concentration factors should be found to 3 significant figures from the provided equations as a function of the given notch sensitivity.After accounting for stress concentration factors, what is the magnitude of the alternating component of the stress in the x direction in units of MPa?[altx]MPa After accounting for stress concentration factors, what is the magnitude of the alternating component of the stress in the z direction in units of MPa?[altz]MPa After accounting for stress concentration factors, what is the magnitude of the mean component of the stress in the x direction in units of MPa?[meanx]MPaAfter accounting for stress concentration factors, what is the magnitude of the mean component of the stress in the z direction in units of MPa?[meanz]MPaWhat is the distortion energy result for the alternating components at the point of analysis in units of MPa?[vonMisesa]MPaWhat is the distortion energy result for the mean components at the point of analysis in units of MPa?[vonMisesm]MPaGiven that ka = kd = 1; ke = 0.814; kc = 0.7 please find the corrected fatigue strength in units of MPa. Please note that kb cannot be assumed to be 1 and should be found for the non-rotating structure.[Se]MPaWhat is the factor of safety for infinite life?[N]
