If end conditions are not given then what should we assume (fixed or free) ? Please explain me.

Bar means tensile loaded mechanical element if it cools tensile stress are developed(imagine).

Arpit said:   9 years ago
If the bar is not fixed, no stress but if it fixed then tensile stress. Data inadequate. !

If the temperature of the bar is lowered, then the nature of stress & strain will be?

When a body is cooled at -5c create the compressive load its solidly correct.

VIPIN said:   1 decade ago
If the load is compressive the stress is also produced is compressive stress.

Chirag said:   8 years ago
Stress=load/area and is independent of temperature so no stress will develop.

Compressive stress is the right answer because no specific case is given.

Deepak said:   8 years ago
No, stress is formed within the bar when cooled unless the bar is fixed.

Akki said:   1 decade ago
Why if bar is cooled then bar in compressive stress? Please explain me.
