Thermal resistance circuits model heat transfer in systems, illustrating how heat flows through materials.

• Identify components: Include heat sources, resistances, and sinks.

• Use series and parallel configurations: Series resistances add up, while parallel resistances combine inversely.

• Example: A wall with insulation can be modeled with resistances for the wall and insulation layers.

• Consider units: Use consistent uni...read more

Stress in engineering refers to the internal force experienced by a material or structure due to external loads.

• Stress is a measure of the intensity of the internal forces within a material or structure.

• It is caused by external loads or forces acting on the material or structure.

• Stress can be categorized into different types such as tensile, compressive, shear, and bending stress.

• Tensile stress occurs when a mater...read more

Aluminium is less suitable for laser cutting due to its high reflectivity and thermal conductivity.

• Aluminium has a high reflectivity, which means it reflects a significant amount of laser energy instead of absorbing it.

• Its high thermal conductivity causes the heat generated during laser cutting to quickly dissipate, making it difficult to achieve precise cuts.

• Aluminium also forms an oxide layer on its surface, whi...read more

Increasing coefficient of friction in rolling process will result in increased resistance and reduced efficiency.

• Increased coefficient of friction leads to increased resistance between the rolling object and the surface it is rolling on.

• This increased resistance results in more energy being lost as heat and less energy being transferred to useful work.

• The rolling process becomes less efficient as more force is req...read more

Throat thickness of steel members as per IS Code varies based on the size of the member.

• Throat thickness is the minimum thickness of the weld at the root of the joint.

• As per IS 800:2007, the throat thickness of fillet welds should be at least 0.7 times the size of the smaller member being joined.

• For example, if the size of the smaller member is 10 mm, the throat thickness of the fillet weld should be at least 7 mm...read more
