A protractor is used to draw and measure angles. An angle is the amount of turn between two lines. Angles are measured in degrees with the symbol °. Angles can be labelled with 3 letters (eg DEF ...

Angle of Repose(θ R): The angle between the surface of the powder pile and the horizontal plane to which a material can be piled without slumping is called the angle of repose. θ R = tan-1 (h/r) Angle ...

Abstract: The problem of measuring differential angle of arrival through two relatively small apertures of variable separation is considered. The motivation is to evaluate the practicality of a ...

This project measures unintended properties of a brushless motor which change as the motor angle is turned to determine it's angle. The project is currently beta, and as such has limitations: It must ...
