A cantilever beam of circular cross-section is made of alloy steel is subjected to a fluctuating load that varies from -F to 2F. Determine the minimum ultimate strength of the beam material which can withstand the fluctuating loads. The variable forces on the beam induce corresponding fluctuating stresses between + 48 N/mm2 to -24 N/mm?. Assume the following values. Yield strength = 0.55 ultimate strength, endurance stress = 0.45 ultimate strength. Take a factor of safety = 2. Use Soderberg relation in your design i) Calculate mean and alternating stress ii) Calculate endurance strength **Note: Please upload your handwritten working/solution to the link provided. Mean Stress in N/mm^2 ... Variable Stress in N/mm^2 ... Endurance Strength in N/mm^2 .. Ultimate Strength in N/mm^2..
