Answer:
88.9mpa
Explanation:
do = outer diameter = 300mm
di = inner diameter = 200 mm
Sy = yield strength = 320 mpa
To get maximum pressure
-45000/22500-10000
= 45000/12500
= -3.6po
Sy = 3.6Po
Po = 320/3.6
Po = 88.9mpa
88.9 Mpa is the maximum pressure that would cause the material of the tube to yield
