(b) A cantilevered beam of length 300 mm and rectangular cross-section is carrying a fluctuating force of (Fmax = 3.5 kN, R = 0.1) as shown in Figure Q1. The beam material is AISI 1038 normalized steel. Taking the geometrical stress concentration factor of the fillet at the fixed end, K, = 1.5, show that the beam remains elastic. 300 mm Figure Q1 (Fmax, R) 40 mm 20 mm 1

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.
