Acold-drawn aisi 1015 steel tube is 300 mm od by 200 mm id and is to be subjected to an external pressure caused by a shrink fit. what maximum pressure would cause the material of the tube to yield? . syt = syc = 600 mpa.

The maximum pressure= 230.76 M Pa

Explanation:

Given that

Outer diameter=300 mm

Inner diameter=200 mm

Condition for thick cylinder:

    If thickness of cylinder is greater than 1/20 times of internal diameter,Then it is called thick cylinder.

We know that when thick cylinder is subjected to external pressure ,the hoop stress given as

Now by putting values

For safe design

So 2.6 P <600

P<230.76 MPa

So the maximum pressure= 230.76 M Pa

it was a fall down when it happens

explanation:
