A simple curve is connected by tangents that make an angle of 64°. A point “e” along the curve is 220 m along the back tangent and 56 m perpendicular (offset) to the said tangent. The beginning of the curve is located at 9+070. a. What is the radius of the curve? b. What is the tangent distance of the curve? c. What is the length of the long chord? d. What is the station of point “e”? Draw and plot the curve. Compute all of the necessary elements of the curve. Include the proper units/dimensions and round-off the answers to 3 decimal places.
Basic Terminologies
Terminology is a systematic study for the implementation of the terms or words and their correspondence within their respective domain of human activity in the case of multilingual (more than 2) or bilingual (2) languages. Terminology is defined as the study of concepts, conceptual related phrases or expressions, and lexicography, on the other hand, is the discipline used to study any type of word and its meaning. Technical ventures and institutes create and gather their resources or word collection also known as a Glossary.
Common Units Of Pressure
Pressure is something that we experience in daily life but fail to recognize it as our body is so accustomed to it. For example, the atmospheric air applies pressure on our body, but we don’t feel it as we are exposed to it since birth and our body is habitual to it. When we write using a pen, we need to apply some pressure over the pen to make it start writing. But these are our day-to-day activity which we fail to recognize
