22.
A compound cylinder with inner radius 50 mm and outer radius 70 mm is made by shrinking one cylinder on to the other cylinder, The junction radius is 60 mm and the junction pressure is 1.1 N/mm2. The maximum hoop stress developed in the inner cylinder is
3.6 N/mm2 compression
3.6 N/mm2 tension
7.2 N/mm2 compression
7.2 N/mm2 tension

Max. hoop stress = -2 * 1.1 * √(60)/√(60) - sqr(50) = -7.2 N/mm2.

I'm unable to understand this. Please anyone explain me.

Hoop Stress= -2p (R2)^2/[(R2)^2 - (R1)^2].

Where,
R1 = 50.
R2 = 60.
p = 1.1.
