Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Question

M = 150 [Nm]

Problem 1:
The figure presented below shows a grooved rotating shaft with a ground surface finish that is
subjected to a constant bending moment of M = 150 [Nm] and an axial load of P = 10 [kN]. In
addition, there is a torsional load that fluctuates between -50 < T < 130 [Nm]. It can be assumed
that the torsional loading is in phase and acting at the same frequency as the rotation of the shaft.
The radius of the fillet is r = 3 [mm] and a reliability of 90% is desired. The shaft is made from
steel having Sut= 935 [MPa] and Sy = 880 [MPa]. Find the safety factor for both the infinite
fatigue life (n.) and for 3 x 105 cycles (n3x105).
