Why is it important that a low amount of current is sent to the base of a transistor? By sending varying levels of current from the base, the amount of current flowing through the gate from the collector may be regulated. In this way, a very small amount of current may be used to control […]
What is mechatronics and control engineering?
What is mechatronics and control engineering? Mechatronics is the synergistic combination of mechanical engineering, electronics, control engineering and computer science. Thus, mechatronics engineering carries the potential to make major impacts upon various industries such as automotive, consumer electronics, biomedical and robotics/automation. Where can a mechatronic engineer work? Mechatronics engineers can work in many industries, but […]
Which measure of variation is most reliable?
Which measure of variation is most reliable? standard deviation How do you choose the best measure of dispersion? The interquartile range is usually preferable, as it is more informative than the range. Data measured at the interval/ratio level: All three measures of dispersion we have examined are appropriate. The standard deviation is usually preferable. What […]

What is regression equation in statistics?
What is regression equation in statistics? A regression equation is a statistical model that determined the specific relationship between the predictor variable and the outcome variable. A model regression equation allows you to predict the outcome with a relatively small amount of error. What does regression analysis measure? Regression is a statistical method used in […]
What happens if brake rotors are too thin?
What happens if brake rotors are too thin? When a rotor is too thin, it overheats and warps, leading to an annoying vibration or pedal pulsation. When rotors were thicker, they could take the wear from the brake pads, be machined and still have enough metal left to dissipate the heat. What causes brake rotors […]
How are density and specific gravity related?
How are density and specific gravity related? specific gravity: Relationship Between Specific Gravity and Density. If the densities of the substance of interest and the reference substance are known in the same units (e.g., both in g/cm3 or lb/ft3), then the specific gravity of the substance is equal to its density divided by that of […]
How do you calculate shear stress in a beam?
Why is it important to have a space management system while driving?
Why is it important to have a space management system while driving? Space management is the cornerstone of defensive driving. It will allow you to gather the maximum amount of visual information about the road, ensure the most important details do not escape your attention and give you the necessary time to make sound judgments […]
What are taxes and subsidies?
What are taxes and subsidies? While a tax drives a wedge that increases the price consumers have to pay and decreases the price producers receive, a subsidy does the opposite. A subsidy is a benefit given by the government to groups or individuals, usually in the form of a cash payment or a tax reduction. […]
