A steel pipe 10 feet long is able to withstand 15 tonnes of tensile load. Can you trust this pipe to withstand a 15 tonne compressive load?

Vivek

• Jul 10th, 2016

May or may not, it will depend upon Shape of cross section (moment of inertia), end condition if it is going under buckling instability, and if it is behaving as short column then based upon cross section available we can say whether it will suffice for new load (15 ton)?

k.dinesh

Steel pipe having only tension property. so it has small compressive property. so it does not trust the compressive load upto 15 tonnes
