Acantilever of length 0.5 m and square cross-section of sides 50 mm is subjected to a downward-acting alternating end load. the static tensile yield and fatigue strengths for completely reversed stress of the material are 300 mpa and 200 mpa. if the mean stress σm= 30 mpa, using the soderberg equation determine the maximum and minimum values of the end load. also show stress-time variation curve (sinusoidal).
