A compound tube consist of a steel tube 140mm internal diameter;160 mm external diameter; then outer brass tube 160mm internal diameter ; 180mm external diameter the 2 tubes are of the same length The compound tube carries a external load of 900kn find the stress the load carried by each tube ; the compoud is shortends length of each tube is 140 mm .

Answer 1

Answer:

volume of tube = πh(R² - r²)

22/7 x 140 x (90² - 80²)

440 x (8100 - 6400)

440 x 1700

748000m²

after this i was unable to understand you question
