What is draft fan? Forced Draft Fan is a type of a fan supplying pressurized air to a system. This fan supplies air to the Air-Preheater, where it captures the heat from the flue gases coming from the Boiler Outlet. What is the ID fan? Induced draft fans or ID fans are used in systems […]
What is assemble to order strategy?
What is assemble to order strategy? Assemble-to-order (ATO) is a business production strategy where products that are ordered by customers are produced quickly and are customizable to a certain extent. It typically requires that the basic parts of the product are already manufactured but not yet assembled. What are characteristics of the make to order […]
What is the horizontal acceleration of a projectile?
What is the horizontal acceleration of a projectile? The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent […]
How does high density altitude affect performance?
How does high density altitude affect performance? Because high density altitude has a detrimental impact on aircraft performance. It reduces lift and impairs propeller efficiency, reducing thrust as a result. High density altitude can also decrease the engine’s power output. How does density altitude affect stall speed? As air density decreases with increasing altitude, more […]
What are examples of engineering controls?
What are examples of engineering controls? Engineering controls protect workers by removing hazardous conditions or by placing a barrier between the worker and the hazard. Examples include local exhaust ventilation to capture and remove airborne emissions or machine guards to shield the worker. What are the three engineering controls? Engineering controls consist of a variety […]
What are the processes of Otto cycle?
What are the processes of Otto cycle? The Otto cycle consists of isentropic compression, heat addition at constant volume, isentropic expansion, and rejection of heat at constant volume. What are the major processes in the air-standard Otto cycle? The Otto cycle is an air-standard cycle which approximates the processes in petrol or diesel engines. It […]
What is the main role of engineer?
What is the main role of engineer? Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. What statement best describes what engineers do? Explanation: The engineers […]

What is the difference between yield stress and proof stress?
What is the difference between yield stress and proof stress? The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically. In such a case, the offset yield point (or proof stress) is taken as the stress at which […]
What is twinning in plastic deformation?
What is twinning in plastic deformation? In twinning each plane of atoms move through a definite distance and in the same direction. When a shear stress is applied the crystal will twin about the twinning plane in such a way that the region to the left of the twinning plane is not deformed where as […]
