What is the difference between open loop and closed loop system? The main difference between an open-loop system and a closed-loop system is that the closed-loop system has the ability to self-correct while the open-loop system doesn’t. Consequently, closed-loop systems are often called feedback control systems while open-loop systems are also known as non-feedback controls. […]
What is the input movement and output movement of a chain drive?
What is the input movement and output movement of a chain drive? In a Chain Drive the input and output shafts are always parallel. The input and output gears move in the same direction since their teeth are not meshed. Both gears are circles therefore the input and output gears type of movement is Rotary […]

How do you prevent stress corrosion from cracking?
How do you prevent stress corrosion from cracking? Stress corrosion cracking can be prevented through: Avoid the chemical species that causes SCC. Control of hardness and stress level (residual or load). Introduce compressive stress by shot-peening for example. Use of materials known not to crack in the specified environment. What is water line corrosion? Waterline […]
What should you do if you are exposed to hydrogen sulfide?
What should you do if you are exposed to hydrogen sulfide? Treatment. Those exposed to H2S gas should remove themselves from the toxic environment immediately. Rescuers need to take caution when approaching victims who cannot evacuate independently, as to not be harmed themselves by H2S exposure. What are three symptoms you would experience if you […]
What would cause a transmission to lock up?
What would cause a transmission to lock up? This condition can also be caused by low transmission fluid, contamination due to lack of maintenance or water intrusion, or internal wear and tear on the transmission parts inside the transmission. A high revving engine is a typical sign that you have worn clutches or other parts […]

How do you know if power factor is leading or lagging?
How do you know if power factor is leading or lagging? The key factor of differentiation between leading and lagging power factor is that leading power factor is attained when the load current is in the leading position to that of the supply voltage. While lagging power factor shows that the current lags the voltage […]
