Which of the following yielding criteria is more conservative for ductile materials? Of the failure criteria, the Tresca is the most conservative for all materials, the von Mises the most representative for ductile materials, and the Rankine the best fit for brittle materials. Which is most suitable theory of failure for ductile materials? 83 – […]
How do we get the impulse response function H T of a system given a system equation?
How do we get the impulse response function H T of a system given a system equation? Given the system equation, you can find the impulse response just by feeding x[n] = δ[n] into the system. If the system is linear and time-invariant (terms we’ll define later), then you can use the impulse response to […]
How do you calculate voltage drop in a series circuit?
What can the speaker do to help the audience better receive the message?
What can the speaker do to help the audience better receive the message? Key Points The speaker can direct the attention of the audience to what is important by using changes in rate and volume, body movement, and gesture to emphasize what is important. It is important to read the non-verbal clues of the audience […]
What is the efficiency at maximum power transfer condition?
What is the efficiency at maximum power transfer condition? The efficiency is only 50% when maximum power transfer is achieved, but approaches 100% as the load resistance approaches infinity, though the total power level tends towards zero. Efficiency also approaches 100% if the source resistance approaches zero, and 0% if the load resistance approaches zero. […]
What element is a semiconductor?
What element is a semiconductor? silicon How can you increase the conductivity of metals? There are many reasons for electroplating. It can enhance a component’s strength, solderability, and corrosion-resistance. Electroplating can also improve the electrical conductivity of a base material.৪ অক্টোবর, ২০১৮ How does impurity affect the conductivity of a semiconductor? Adding small amounts of […]
Which of the following is an essential safety procedure that protects workers from injury while working on or near electrical circuits and equipment?
Which of the following is an essential safety procedure that protects workers from injury while working on or near electrical circuits and equipment? Lock-out/tag-out What are the most common electrical safety issues that safety professionals encounter? The following hazards are the most frequent causes of electrical injuries: contact with power lines, lack of ground-fault protection, […]
What factors influence the final properties of composites?
What factors influence the final properties of composites? The reconfiguration of the composite structure depends on many parameters, such as the material properties, lay up sequence, fiber orientation, thickness, and the strategic position of laminae with different orientations. What do the properties of composite materials depend upon? The mechanical properties of composite materials usually depend […]
Why is RAM faster than rom?
Which materials are good conductors and which are good insulators?
Which materials are good conductors and which are good insulators? Wool, dry air, plastics, and polystyrene foam are all examples of good insulators. Materials that do not insulate well are called conductors. Conductors have loose bonds that allow particles to move easily and transfer energy from one particle to the next. Metals tend to be […]
