Unformatted text preview: Note: If you absolutely cannot get the shear or moment for problem 1, you may use Mmax = 300 kft, and Vmax = 40 kips. This will of course cost you, but its better than nothing. Problem 4) Design the lightest steel pipe flagpole to carry a load of 60 kips on its top without buckling. The pole is 18 feet tall, and can be no bigger than 6 inches in diameter. Use a factor of safety of 2.5. Problem 5) Determine the value of the Kern limit for a circular footing of diameter D. For those bums who didn’t come to class that day, the Kern limit tells how far the vertical load P can move off the center of the footing without causing tension in the soil, which of course the soil cannot take....
