Question

____________________stress will be developed if the temperature of a cantilever beam is incresded.

• A. Tensile
• B. Compressive
• C. No thernamal
• D. Both tensile and compressive

Answer 1

Answer:

C. No thernamal

When the temperature of a cantilever beam is increased, no thermal stresses will be developed because there is no restriction to expansion at one end. Thermal stress only occurs when there is external force preventing free expansion or contraction. An increase in temperature produces positive thermal strain and an increase in length, but without restriction, there will be no thermal stresses.
