Tangential and normal components print that page

vector can be decomposed uniquely as a sum of two vectors, one tangent to the curve, called the tangential component of the vector, and another one perpendicular to the curve, called the normal component of the vector. Similarly a vector at a point on a surface can be broken down the | 2011/3/11 10:55:17

Tangential angle print that page

In geometry , the tangential angle of a curve in the Cartesian plane, at a specific point, is the angle between the tangent line to the curve at the given point and the x -axis. [ 1 ] (Note, some authors define the angle as the deviation from the direction of the curve at some fixed starting | 2010/9/25 7:44:44

Turning print that page


either on the outside of the cylinder or on the inside (also known as boring ) to produce tubular components to various geometries. Although now quite rare, early lathes could even be used to produce complex geometric figures, even the platonic solids ; although until the advent of CNC it

Ex-tangential quadrilateral print that page

In geometry , an ex tangential quadrilateral is a convex quadrilateral where the extensions of all four sides are tangent to a circle outside the quadrilateral. [ 1 ] It has also been called an exscriptible quadrilateral . [ 2 ] The circle is called its excircle or its escribed circle | 2011/8/29 4:26:10

Euclidean vector print that page

In elementary mathematics , physics , and engineering , a Euclidean vector (sometimes called a geometric [ 1 ] or spatial vector , [ 2 ] or – as here – simply a vector) is a geometric object that has both a magnitude (or length ) and direction. A Euclidean vector is frequently represented | 2011/9/22 12:34:44

Centrifugal force (planar motion) print that page

In classical mechanics , centrifugal force (from Latin centrum "center" and fugere "to flee") is one of the three so-called inertial forces or fictitious forces that enter the equations of motion when Newton's laws are formulated in a non-inertial reference frame . The other two fictitious | 2010/9/25 3:03:54

Polarization (waves) print that page


wave's polarization is more complicated, as the fields can have longitudinal as well as transverse components . Such EM waves are either TM or hybrid modes . For longitudinal waves such as sound waves in fluids , the direction of oscillation is by definition along the direction of travel
