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

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
