! USE THE GIVEN DATA !
The steel pipe is supported on the circular base plate and concrete pedestal. If the normal failure
stress for the steel is (sfail)st = 350 MPa, determine the minimum thickness t of the pipe if it
supports the force of 500 kN. Use a factor of safety against failure of 1.5. Also, find the minimum
radius r of the base plate so that the minimum factor of safety against failure of the concrete due
to bearing is 2.5. The failure bearing stress for concrete is (sfail)con = 25 MPa.
