A) provide a rough sketch of the proposed shaft geometry indicating where you would put the changes in diameter in the shaft.
b) (5) select shaft material
c) (30) determine proper shaft diameter based on stress for each side of the bearing at a for the safety factor of 1.5. indicate failure theory and why you chose that theory.
d) (15) if the load was doubled, how many revolutions would be expected before failure

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

answer is 144

step-by-step explanation:

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
