The columns whose slenderness ratio is less than 80, are known as
A. Short columns
B. Long columns
C. Weak columns
D. Medium columns
Because in spherical shell hoop stress is pd/4t, therefore, thickness(t ) = pd/4 * hoop stress
but in cylindrical shell it is= pd/ 2* hoop stress.
Therefore thickness more in the cylindrical shell for the same stress.
