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 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 […]

What does check electronic throttle control mean?
What does check electronic throttle control mean? These days, it’s all electronic — and that means that when something goes wrong with the throttle, you’ll see a warning light on your dash. The throttle control warning light will normally light up briefly each time you start your vehicle, and then go off. What does the […]
What is the difference between atmospheric pressure and gauge pressure?
What is the difference between atmospheric pressure and gauge pressure? Atmospheric pressure is a measure of absolute pressure and is due to the weight of the air molecules above a certain height relative to sea level, increasing with decreasing altitude and decreasing with increasing altitude. Gauge pressure is the additional pressure in a system relative […]
