Engineering Mechanics Statics Theory Vector Magnitude And Uni Engineering mechanics: statics theory | vector magnitude and unit vectorsthanks for watching :)video playlists:theory playlist?list=pll. A unit vector is a vector with a magnitude of one and no units. as such, a unit vector represents a pure direction. by convention, a unit vector is indicated by a hat over a vector symbol. this may sound like a new concept, but it’s a simple one, directly related to the unit circle, the pythagorean theorem, and the definitions of sine and cosine.

Engineering Mechanics Statics Theory Adding Cartesian Vectors 1.3.4 vector math. here’s more official language to describe vectors: vectors can be added together and multiplied by scalars. vector addition is associative and commutative, and vector multiplication by a sum of scalars is distributive. also, scalar multiplication by a sum of vectors is distributive: α(→a →b) = α →a α→b α (a. Unit vectors are vectors with a magnitude of one (unitless), and scalar components are signed values with units. together, they fully define a vector quantity; the unit vector specifies the direction of its line of action, and the scalar component specifies its magnitude and sense. the scalar component “scales” the unit vector. Vectors use components, magnitude, and direction (unit vector) to do so. application: a hammock hangs at an angle from the wall. when a person is in the hammock, they are pulling on the wall with a force at an angle. this force vector could be componentized into x and y, using the angle and the weight of the person to calculate it. Mechanics: newton’s three laws of motion. second law: a particle of mass “m” acted upon by an unbalanced force “f” experiences an acceleration “a” that has the same direction as the force and a magnitude that is directly proportional to the force. f = ma. second law forms the basis for most of the analysis in dynamics.

In general, f = f ˆf, where f is the magnitude of f, and ˆf is the unit vector pointing in the direction of f. solving equation (2.5.1) for ˆf gives the approach to find the unit vector of known vector f. the process is straightforward— divide the vector by its magnitude. for arbitrary vector f. ˆf = f | f |. A unit vector is a vector with a length of one (unitless) which points in a defined direction. hence, a unit vector represents pure direction, independent of the magnitude and unit of measurement. the scalar component is a signed number with units which may be positive or negative, and which defines the both the magnitude and sense of the.
