Which is a work producing device? Flow devices containing moving components for work out: Turbine. Produces mechanical work from an incoming high-pressure stream. Often approximated as adiabatic. Term often used for turbines with nontrivial heat transfer. Why is the work greater for a reversible process than for an actual process? The reason why more work […]
What is the US customary unit for temperature?
What is the US customary unit for temperature? The U.S. customary measurement unit for temperature is °Fahrenheit. Customary system is called the International System of Units or the Modern Metric System. Which unit of measurement is used in the US customary system? In math, the customary system can be defined as a set of weights […]
What is the easiest way to prevent overexposure to fumes and gases?
What is the easiest way to prevent overexposure to fumes and gases? Q: How can you keep fumes and gases away from your breathing zone? A: Keep fumes and gases from your breathing zone and general area using natural ventilation, mechanical ventilation, fixed or moveable exhaust hoods, or local exhaust at the arc. What is […]
What does the brake pedal use leverage for?
What does the brake pedal use leverage for? Leverage, also called mechanical advantage, is used by the brake pedal assembly and by drum brake systems. Fluid, under pressure, transmits both force and motion. Electronics provide antilock braking and traction control functions. When the brake pedal is depressed a pushrod transfers the force to a hydraulic […]
How do you find the resistance of an ac circuit?
How did the Wright brothers think of the airplane?
How did the Wright brothers think of the airplane? If others had thought about steering at all, it was by rudder – a marine analogy unworkable in the air. The Wrights saw that control and stability were related, that a plane turned by rolling. Six hundred more glides that year satisfied them that they had […]
What is the probability of rolling a 1 on a 6 sided die?
What is meant by SHM?
What is meant by SHM? Simple harmonic motion is defined as a periodic motion of a point along a straight line, such that its acceleration is always towards a fixed point in that line and is proportional to its distance from that point. What is oscillatory motion give examples? Oscillatory motion is defined as the […]
What is tie line in phase diagram?
What is tie line in phase diagram? page 2 of 9. An isothermal (constant temperature) line through the alloy’s position on the phase diagram when it is in a two phase field, intersecting the two adjacent solubility curves, is called a tie line (yes, that’s the horizontal yellow line on the diagram). What is tie […]
