A short column composed of two standard steel pipes is subjected to a load P= 20 kips, as shown in Fig. P9-6. Determine the compressive stress in each pipe. Neglect the weight of the pipes. Determine the size of steel rod, to the nearest sixteenth of an inch, needed to support a tensile load of 40 kips if the allowable tensile stress of steel is 22 ksi. Determine the size of steel rod, to the nearest mm, needed to support a tensile load of 200 kN if the allow- able tensile stress of steel is 150 MPa.

Answer rating: 100% (QA)

SOLUTION To determine the compressive stress in each pipe we need to calculate the crosssectional area of each pipe and then divide the load P by the respective crosssectional area For the 3inch pipe ... View the full answer
