What is Big O notation with example? Big O notation shows the number of operations Big O notation Example algorithm O(log n) Binary search O(n) Simple search O(n * log n) Quicksort O(n2) Selection sort How is Big O notation used to describe the complexity of algorithms? Big O notation is used in Computer Science […]

What caused the Columbia accident? The cause of the accident was a piece of foam that had fallen off the Shuttle’s external fuel tank during launch. The foam struck the left wing of the shuttle, causing serious damage that ultimately led the vehicle to disintegrate when it reentered Earth’s atmosphere. What went wrong in the […]

What is the most widely used arc welding process in the world? Gas Metal Arc Welding (GMAW/MIG) This style of welding is also referred to as Metal Inert Gas (MIG). It uses a shielding gas along the wire electrode, which heats up the two metals to be joined. This method requires a constant voltage and […]

What are the parts of a number called? called the decimal point. The digits lying to the left of the decimal point form the whole number part. The decimal point together with the digits lying on the right of decimal point form the decimal part. How do you find the part of a number? Divide […]

What is the meaning of shear stress? Shear stress, force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress. The resultant shear is of great importance in nature, being intimately related to the downslope movement of earth materials and to earthquakes. Is shear stress a […]

Can you get saturated air from unsaturated air? Certainly. Just lower the temperature of unsaturated air to the point of saturation. That is possible with any air that contains more than zero moisture. At some point the air will be saturated since saturation occurs with less moisture at a lower temperature. How is saturated air […]

What size hydraulic pump do I need for a log splitter? If you are serious about making your own backyard log splitter, then you want to have, at a minimum, the following components to provide the right amount of force and power for basic splitting of averaged sized, seasoned logs: A 5 Horsepower engine. A […]

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? 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? 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 […]
