circumferential tensile stress

140) The thickness of a thin cylindrical shell with hemispherical ends is ______ that of spherical ends.

Answer is:

more than

141) Lame's theory is associated with

Answer is:

thick cylindrical shells

Explanation:

If the thickness of the wall of a shell is greater than 1/10 of its diameter, it is known as thick shell.

The thick shells are, generally, used to withstand high pressures. Sometimes, even, compound thick shells are used to withstand very high pressures or to contain chemicals under high pressure.
The problem of thick cylinders is, somewhat, complex and is solved by Lame's theory.

142) In a thick cylindrical shell subjected to an internal pressure, the tangential stress across the thickness of a cylinder is

Answer is:

maximum at the inner surface and minimum at the outer surface
