Assume the following:

• The forces act at a radius of 0.06m
• F_t is 4,180N
• The diameter of the shaft is 0.03m
• F_a is 1,460N
• The distance from the point the forces act at to support A is 0.122m
• F_r is 2,402N and
• The distance from the point the forces act at to support B is 0.048m

What is the ratio of the average stress to the alternating stress at the critically loaded section?

Answer to 3 decimal places and a 1% error is allowed for.
