What is the difference between engineering stress and strain and true stress and strain?
What is the difference between engineering stress and strain and true stress and strain? Stress/Strain graph of a tension test experiment. True stress is the applied load divided by the actual cross-sectional area (the changing area with time) of material. Engineering stress is the applied load divided by the original cross-sectional area of material. How […]
How does the EPA affect environmental policy?
How does the EPA affect environmental policy? From the EPA’s creation, it has sought to protect and conserve the natural environment and improve the health of humans by researching the effects of and mandating limits on the use of pollutants. The EPA regulates the manufacturing, processing, distribution, and use of chemicals and other pollutants. What […]
Which is a work producing device?
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 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 […]
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 is constant head permeability test?
What is constant head permeability test? The constant head permeability test is a laboratory experiment conducted to determine the permeability of soil. The soils that are suitable for this tests are sand and gravels. Soils with silt content cannot be tested with this method. The test can be employed to test granular soils either reconstituted […]
What is IEEE floating-point representation?
What is IEEE floating-point representation? The IEEE-754 standard describes floating-point formats, a way to represent real numbers in hardware. In single-precision and double-precision formats, there’s an assumed leading 1 in the fractional part. The fractional part is called the significand (sometimes known as the mantissa). What is the representation for IEEE single precision floating-point number? […]
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 […]
