What are the factors that affect surface finish?
What are the factors that affect surface finish? The factors that affect surface finish are (1) geometric factors such as type of operation, feed, and tool shape (nose radius in particular); (2) work material factors such as built-up edge effects, and tearing of the work surface when machining ductile materials, which factors are affected by […]
Why is it necessary for the wheel balancing machine to be in a good working condition?
Why is it necessary for the wheel balancing machine to be in a good working condition? If your wheels are in perfectly working condition, then you should not feel any vibrations in your steering wheel. When the weight of car is uneven and not balanced, it creates a heavy spot that makes your tires wear […]
What is the difference between manual and power brakes?
What is the difference between manual and power brakes? There are brakes with no power assist (aka manual brakes) and brakes WITH power assist (aka power brakes). The only difference between power and manual brakes is the addition of a brake booster, which uses engine vacuum to help you apply pressure to the brake pedal. […]
What is a pneumatic transducer?
What is a pneumatic transducer? Electro-pneumatic transducers convert a current or voltage input into proportional output pressure. They are often paired with valves, pneumatic relays, and flow regulators in process control applications. Adding the span to the zero value yields the maximum output pressure for a calibrated device. What is electronic transducer? Essentially a transducer […]
What is C++ useful for?
What is C++ useful for? When we require very high-level mathematical computations, performance and speed become important. Hence most of the libraries use C++ as their core programming language. Apart from speed and performance, C++ is also close to hardware and we can easily manipulate hardware resources using C++ low-level functions. Is C++ useful in […]
What is total harmonic distortion in audio amplifiers?
What is total harmonic distortion in audio amplifiers? Total Harmonic Distortion + Noise (THD + N) is a measure of just how much effect the amplifier has on the sound output. The lower this figure, the closer the output of the amplifier will sound to the original recording. How much total harmonic distortion is acceptable […]
What load types deep groove ball bearing can be used?
What load types deep groove ball bearing can be used? Features of Deep-Groove Ball Bearings They can withstand a radial load and a limited axial (or thrust) load. In short, deep-groove ball bearings are a good option if there will be pressure applied to the bearing from both the side of a shaft (radial) and […]
What are used to prevent soil movement and cave-ins during the excavation of earth?
What are used to prevent soil movement and cave-ins during the excavation of earth? Sloping involves cutting back the trench wall at an angle inclined away from the excavation. Shoring requires installing aluminum hydraulic or other types of supports to prevent soil movement and cave-ins. Is a trench considered a confined space? Some examples of […]
