The single-stepped shaft shown below has a $$D=12.7\mathrm{mm},d=6.35\mathrm{mm}$$, and $$r=0.76\mathrm{mm}$$. Calculate: (a) The nominal tensile stress in the shaft $$\left({?}_{\text{nom }}\right)$$ if an axial load of $$5600\mathrm{N}$$ is applied to the shaft. (b) The ratio of the diameters (c) The ratio of the radius to the diameter (d) The stress concentration factor, $${\mathrm{K}}_{\mathrm{t}}$$. (e) The maximum tensile stress in the shaft $$\left({?}_{\max }\right)$$ if an axial load of $$5600\mathrm{N}$$ is applied to the shaft. Please observe all units - some may need to be converted to obtain the answer in the correct magnitude. - The nominal tensile stress in the shaft $$\left({?}_{\text{nom }}\right)$$ : $$\mathrm{MPa}$$ - (Enter the number as an integer with no decimal places (Example: 12). (b) Answer - The ratio of the diameters: - (Enter the number as one digit and two decimal places (Example: 1.23.) (c) Answer - The ratio of the radius to the diameter: - (Enter the number as one digit and two decimal places (Example: 1.23.) (d) Answer - The stress concentration factor, $${\mathrm{K}}_{\mathrm{t}}$$ : - (Enter the number as one digit and two decimal places (Example: 1.23.) (e) Answer - The maximum tensile stress in the shaft $$\left({?}_{\max }\right)$$ : $$\mathrm{MPa}$$ - (Enter the number as three digits and no decimal places (Example: 123).)
