how sine function used in civil engineering field?

Answer 1

sine and cosine functions are used everywhere in civil engineering. A basic first course in civil engineering, Statics, deals with structures that do not move, like a bridge or a building. In this course, for example, one of the first basic rules is the concept of equilibrium, which states that for a structure in equilibrium(i.e. not moving), the sum total of all forces acting on the structure must equal zero. Well, in a 3 dimensional world, you have 3 different directions(north/south, east/west, up/down), and these are usually represented as the x,y, and z axis. Since most forces aren't usually pointing exactly n/s e/w or u/d, they are pointed diagonally to some degree. So whet engineers do is they use the Pythagorean theorem(a^2 + b^2 = c^2) to break down each force into x,y, and z components. To do this, they have to use the sine and cosine functions. Then, according to equilibrium:

the sum of all forces' x components = 0
the sum of all forces' y components = 0
the sum of all forces' z components = 0

Breaking down diagonal forces into x,y, and z components is basic to many engineering fields, not just civil engineering.

Answer 2

trigonometry is used by using engineers a good form of homes are performed by using computing their top applying trigonometry , trigonometry is the explanation why an engineer can degree the size or the size of the development with out even travelling around the full development yet another considerable functionality off trigonometry is fixing areas of strange lands. there are lot of strange land, and if so, the land is divided into triangles so as that area might nicely be obtained relatively. what matters in trig are being in touch? plenty! sine regulation, cosine regulation, heron's formula and a good form of alternative specific formula as long right this moment approximately triangles, trigonometry is on its way yet another, is approximately celestial trigonometry, between the main useful trigonometry, use in estimating area of celestial bodies and could be a useful gadget in predicting the subsequent asteroid passing by using earth i've got been handling precise Triangle Trigonometry and oblique triangle Trigonometry and we've been applying this to remedy distances of boats from the port interior of a definite quantity of time, we used formula to remedy the top of the development with the attitude of elevation given, we assume the size of the kite with its vertical distance and an attitude given and much extra

Answer 3

Sine functions are used everyday in Civil Engineering.

It is used in Statics for find and solve for forces; in Mechanics of Materials to study stress, strain and shear forces; in Structures to study how structures react to forces like wind loads, dynamic loading, water loading, etc; even in roadway design to layout curves, slopes, etc.

Answer 4

Sines and cosines are frequently used in geometrical calculations, to make beams the correct length for example.

Sinusoidal waves are useful tools for analyzing structural vibration as well.

Answer 5

Vibration calculations.

Answer 6

mainly to solve triangles
