Strength of Materials MCQ with Answers

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

143) In a thick cylindrical shell subjected to internal pressure p, the radial stress across the thickness of the cylinder is

Answer is:

maximum at the inner surface and zero at the outer surface

144) The maximum tangential stress in thick cylindrical shell is always ______ the internal pressure acting on the shell

Answer is:

greater than
