Which description represents the meaning of the alphabet of lines? The Alphabet of Lines is a list of line symbols that engineers use in technical drawings to communicate specific shapes, sizes or surfaces. The lines and symbols used in the Alphabet of Lines are universal, which means engineers around the world use and understand them. […]
How do you convert analog signal to digital signal?
How do you convert analog signal to digital signal? ADCs follow a sequence when converting analog signals to digital. They first sample the signal, then quantify it to determine the resolution of the signal, and finally set binary values and send it to the system to read the digital signal. Two important aspects of the […]

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 […]
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 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 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 is a feedback control system?
What is a feedback control system? A feedback control system is a system whose output is controlled using its measurement as a feedback signal. This feedback signal is compared with a reference signal to generate an error signal which is filtered by a controller to produce the system’s control input. Which is the output of […]
