What effect does a scale factor equal to 1 have on the dimensions of the image being scaled? In each scaled copy, the sides are a certain number of times as long as the corresponding sides in the original. We call this number the scale factor. The size of the scale factor affects the size […]
Which sorting algorithm is best for sorted array?
Which sorting algorithm is best for sorted array? When the array is almost sorted, insertion sort can be preferred. When order of input is not known, merge sort is preferred as it has worst case time complexity of nlogn and it is stable as well. When the array is sorted, insertion and bubble sort gives […]
Why does steel become brittle at low temperatures?
Why does steel become brittle at low temperatures? Cooling just about anything to liquid nitrogen temperatures makes it more brittle than at higher temperatures. At higher temperatures, defects in the crystal lattice of a material are more mobile. At lower temperatures, the nearby atoms in the crystal lattice do not move and long cracks can […]

What were the problems with the early steam engines?
What were the problems with the early steam engines? Another limitation of early steam engines was speed variability, which made them unsuitable for many textile applications, especially spinning. In order to obtain steady speeds, early steam powered textile mills used the steam engine to pump water to a water wheel, which drove the machinery. What […]
When a fluid flows over an object the pressure or form drag?
When a fluid flows over an object the pressure or form drag? A body moving through a fluid experiences a drag force, which is usually divided into two components: frictional drag, and pressure drag. Frictional drag comes from friction between the fluid and the surfaces over which it is flowing. What does the pressure at […]
How do I choose a chain size?
How do I choose a chain size? Chain Wear Factors Two important factors, resistance to wear and resistance to fatigue, should be considered when determining chain size and quality. Generally, these two factors dictate roller chain life and failure. How do you design a chain drive? Type of Chain. Roller Chain is selected for the […]
