Unformatted text preview: 2. Using equations 4.48a and 4.48b, the stresses are maximum at the inside wall where Since the ratio is greater than 0.1, this is a thick wall problem. ratio 1 = ratio t 0.5 ID = 1. Check wall thickness to radius ratio to see if this is a thick or thin wall problem. 4. Calculate the von Mises effective stress using equation (5.7c). ' b 1b 2 1b 3a -3b 2 + = ' b 16.336 MPa = 5. Using the distortion energy theory, the factor of safety is N b S y ' b = N b 24.5 =...
