If you turn off your HVAC system completely in winter and your home temperature dips to 40 degrees, your furnace will have to run for hours to get it back […]
What is a combined heat and power system?
What is a combined heat and power system? CHP is an energy efficient technology that generates electricity and captures the heat that would otherwise be wasted to provide useful thermal energy—such as steam or hot water—that can be used for space heating, cooling, domestic hot water and industrial processes. What is an example of cogeneration? […]
What is non ohmic Behaviour?
What is non ohmic Behaviour? A non- Ohmic device is one that does not have a constant resistance. A light bulb is a simple example; the filament undergoes huge changes in temperature when current passes through it. Therefore, the resistance of the filament is not constant, rather, it increases with increased current. What can cause […]
What is the difference between traction and hydraulic elevators?
What is the difference between traction and hydraulic elevators? A hydraulic elevator uses an electronic pump that pushes oil into a cylinder where the pressure is increased, pushing a piston and causing the elevator to rise. A traction elevator, on the other hand, uses a system of cables, pulleys, and counterweights to lift the cab. […]

What is pure bending stress?
What is pure bending stress? Pure bending ( Theory of simple bending) is a condition of stress where a bending moment is applied to a beam without the simultaneous presence of axial, shear, or torsional forces. Pure bending occurs only under a constant bending moment (M) since the shear force (V), which is equal to. […]
