Explanation Given information: The radius of the fillet is r = 5 mm . The bar is subjected to a moment of M = 17.5 N-m . Calculation: Calculate the geometric ratio as width to height ratio ( w h ) . w h = 80 mm 20 mm = 4 Calculate the geometric ratio as radius to height ratio ( r h ) . ( r h ) = 5 mm 20 mm = 0.25 Calculate the stress concentration factor using Figure 6-43 in the textbook. Take the stress concentration factor as 1.45 for corresponding ( w h ) = 4 and ( r h ) = 0.25 value. Calculate the maximum bending stress using the using the formula: σ max = K M c I (1) Here, M is moment, c is height between neutral axis to top or bottom of the section, and I is moment of inertia. Consider the c value as ( h 2 ) and I value as ( b h 3 12 ) Modify Equation (1). σ max = K M ( h 2 ) b d 3 12 (2) Substitute 1
