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 […]
What does changing wheel offset do?
What does changing wheel offset do? Changing the offset on a front wheel drive vehicle changes the scrub radius, steering, acceleration and braking. On the other hand, frequently you find rear wheel drive vehicles have a negative offset. Changing the offset changes the scrub radius and how the vehicle steers. What happens if the wheel […]
Can manometer measure atmospheric pressure?
Can manometer measure atmospheric pressure? The most common form of a sealed-tube manometer is the conventional mercury barometer used to measure atmospheric pressure. A manometer can be designed to directly measure absolute pressure. The manometer in Figure 5 measures the pressure compared to zero absolute pressure in a sealed leg above a mercury column. How […]
What is shape factor in heat transfer?
What is shape factor in heat transfer? Shape factor or configuration factor or view factor is the commonly used term for heat transfer between any two bodies participating in radiation. The heat coming from a source of the first may not completely touch the second body since the orientation of two bodies are different. Hence […]
Why is it important that a low amount of current is sent to the base of a transistor?
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 […]
How do you convert a whole number into a fraction?
How do you convert a whole number into a fraction? To convert a mixed fraction to an improper fraction, follow these steps: Multiply the whole number part by the fraction’s denominator. Add that to the numerator. Then write the result on top of the denominator. When a fraction is equal to a whole the numerator […]
Which excerpt from the Maori genealogies and origins in New Zealand best shows how Maori perceive their parents?

Which excerpt from “The Maori: Genealogies and Origins in New Zealand” best shows how the Maori perceive their parents? “We cannot do this,” he said. “Rangi and Papa are our parents. Which details from the myths support […]
What does the CPU stand for?
What does the CPU stand for? Central processing unit What is central processing unit CPU? The computer’s central processing unit (CPU) is the portion of a computer that retrieves and executes instructions. The CPU is essentially the brain of a CAD system. It consists of an arithmetic and logic unit (ALU), a control unit, and […]
