This problem illustrates that the factor of safety for machine element depends on the particular point selected for analysis. Here you are to compute factor of safety, based upon the distortion energy theory, for stress elements at A and B pf the member shown in the figure. This bar is made of AISI 1006 cold drawn steel and is loaded by the forces F=0.55 kN, P=4.0 kN, and T= 25 N.m.
2) The cantilever beam shown has a stepped square cross-section and it is made of steel (E= 210 GPa, G=75 GPa) The cross sectional area and area moment of inertia of the beam 1 are A1= 2.2*103 mm2 and I1= 4*105 mm4 and cross sectional area and area moment of inertia of the beam 2 are A2= 3.1*103 mm2 and I1= 8*105 mm4, respectively. Find the deflection at point A by using Castigliano’s theorem.Şekildeki ankastre kiriş çelik malzemeden yapılmış olup iki kademeli kare kesite sahiptir. Kirişlerden biri...
