Pd/4t = T,
P=?
D=1.5m = 150cm.
t = 1.5cm.
t = 50.
By solving.
50 * 4 * 1.5/150 = 2kg/cm2.
The date is not correct,
If t = 500 or d=.15m,
Then answer will be equal to 20.

Hoop stress = pd/2t.
50*1.5/2*1.5 = 25 partial safety factor 1.25.
25/1.25 = 20.
50*1.5/2*1.5 = 25 partial safety factor 1.25.
25/1.25 = 20.

Longitudinal stress = pd/4t , p=50,d=1.5m, t=1.5cm.
50*1.5/4*1.5=25 for safe partial safety factor 1.25 then 25/1.25=20.
50*1.5/4*1.5=25 for safe partial safety factor 1.25 then 25/1.25=20.

No one has the explanation?

I get just 2kg/cm2 : (kindly someone specifies some complete solution. Please).

By using formula of PD/4t. I can not get a answer 20kg/cm2.
Eneka said:

20 kg/cm2 is the correct answer. I agree.

Tensile stress will develop along the longitudinal Axis so from the formula of longitudinal stress pd/4t.

How can you use that formula?
Anyone explanation.
