Two common specifications for NMR tubes are concentricity and camber. Concentricity refers to the variation in the radial centers, measured at the inner and outer walls. Camber refers to the "straightness" of the tube. [1] Poor values for either may cause poorer quality spectra by reducing the homogeneity of the sample.
Camber is a complex property that can be more fully characterized by an airfoil's camber line, the curve Z(x) that is halfway between the upper and lower surfaces, and thickness function T(x), which describes the thickness of the airfoils at any given point. The upper and lower surfaces can be defined as follows:
In vehicle dynamics, slip angle [1] or sideslip angle [2] is the angle between the direction in which a wheel is pointing and the direction in which it is actually traveling (i.e., the angle between the forward velocity vector and the vector sum of wheel forward velocity and lateral velocity , as defined in the image to the right).
The reelection of Donald Trump as president of the United States promises great changes in the coming new year. However, there are politicians who have chosen to resist Trump and his administration.

“Inside Out 2” tackles this head-on. The movie’s first lesson is simple yet profound: anxiety may not feel good, but it often is good for us. Early in the film, Riley goofs around in the ...
Self aligning torque , slip angle , and camber angle are also shown. Self aligning torque ( SAT ), also known as aligning torque or aligning moment ( Mz , moment about the z direction ), is the torque that a tire creates as it rolls along, which tends to steer it, i.e. rotate it around its vertical axis.
Camber stiffness is a parameter used to describe the camber thrust generated by a tire, and it is influenced by inflation pressure and normal load. [3] The net camber thrust is usually in front of the center of the wheel and so generates a camber torque , twisting torque , or twisting moment . [ 3 ]
