: A 1 in-diameter solid round bar has a groove with a 0.1-in radius machined into it. The bar is made of steel with an ultimate strength of 120 ksi and it is subjected to an axial force that fluctuates between-5.15 kip and 12.85 kip. The static stress concentration factor at the groove is Kt 2.1. (40 points) a) Classify the problem type based on the loading condition. b) Determine the fatigue factor of safety using the Goodman failure criterion....
Problem 1) A 1 in diameter solid round bar has a groove 0.1 in deep with a 0.1 in radius machined into t. The bar is made of AISI 1040 CD steel and is subjected to rotating-bending load and the bending moment is 1800 lbf in. Determine the life of the shaft.
A 1-in-diameter solid round bar has a groove 0.1-in deep with a 0.1-in radius machined into it. The bar is made of AISI 1020 CD steel and is subjected to a purely reversing torque of 1800 lbf • in. For theS-N curve of this material, let f = 0.9.(a) Estimate the number of cycles to failure.(b) If the bar is also placed in an environment with a temperature of 750°F, estimate the number of cycles to failure.
