When adding vector quantities remember that the directions have to be taken into account. The result of adding vectors together is called the resultant. In problems, vectors may be added together by ...

Vectors are added ‘nose to tail’ as shown below. The addition of the vectors is the line from the starting point to the finishing point. Triangles ABC and XYZ are equilateral. X is the midpoint of AB, ...

Abstract: Euler's dynamic equation is derived in vector-dyadic form for a three-degree-of-freedom gyro configuration. This equation is then simplified by means of two approximations which are ...

ABSTRACT: There is a new method of calculating the trajectory of sound waves (rays) in layered stratified speed of sound in ocean without dispersion. A sound wave in the fluid is considered as a ...
