If the eyebolt is made of a material having a yield stress of ?Y = 245MPa , determine the minimum required diameter d of its shank. Apply a factor of safety F. S. = 1.5 against yielding. Express your answer to the nearest mm and include the appropriate units.

Explanation:

Factor of Safety= Material Strength / Design Load

∵ designload =⁰y /F.S

=254/1.5

=163.33Mpa

stress=force / area

=163.33×10⁶N/m²=30000N / π/4d²

d²=233.86×10⁻⁶

d=15.2×10⁻³m

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
