When a bar is cooled to degree Celsius it will develop which stress?

Thermal stress
Explanation: Thermal stress: When a bar or beam is subjected to a change of temperature and its deformation is prevented, the stress induced in the bar is called thermal stress.

When a bar is heated and it is restricted to expand the type of stress developed in the bar is?

If the rod is restricted to increase or decrease in dimensions, stress-induced in the bar which is known as thermal stress. If the rod is free from any restriction, thermal stress is zero, though strain can be present.

When a bar is subjected to a decrease of temperature?

If there is a drop in the temperature of the bar, the bar will try to contract, exerting pull on the wall. At the same time the wall offers equal and opposite reaction exerting pull on the bar which will develop tensile stress in the bar.

How do you tell if a stress is compressive or tensile?

Main Difference – Tensile vs Compressive Stress The type of the stress is determined by the force being applied on the material. If it is a tensile (stretching) force, the material experiences a tensile stress. If it is a compressive (squeezing) force, the material experiences a compressive stress.

When bar is cooled to it will develop?

Thus , this deflection is resisted by the equal and opposite stress i.e. tensile stress. Hence , whenever the bar is cooled, it will develop tensile stress.

What happens when a metal bar is cooled?

When a metal bar is cooled, the vibration of the molecules decreases due to which the spacing between the molecules decreases. Hence, when a metal bar is cooled, length decreases, density increases but the mass remains the same.

When the temperature of a body is increased & expansion is restricted the stress induced will be *?

Thermal stress will develop only if expansion is restricted.

Which of the following beam will develop thermal stress when subjected to a change in temperature?

When a bar is subjected to a change of temperature and its deformation is prevented, which of the following stress is induced?…

What is tensile and compression?

Tension and compression. stress. Tensile stress is the normal force per area (σ = F/A) that causes an object to increase in length. Compressive stress is the normal force per area (σ = F/A) that causes an object to decrease in length.

What is tensile and compressive forces?

Compression, or compressive force, is a force that acts to compress or shorten the thing it is acting on. Tension, or tensile force, is a force that acts to expand or lengthen the thing it is acting on. As a simple example, think of a spring. Thus, a force of compression is acting on it to shorten the spring.

Which of the beams develop thermal stresses on heating?

Thermal stresses in beams are treated in homogeneous beams, composite beams with two and more homogeneous beams, and inhomogeneous beams whose material properties depend on position. Temperatures which vary in the lateral direction to the beam are treated so that only the symmetry deformations are treated.
