moment of inertia

The formula can be used in approximate calculation of instable critical load of high pier in the design and construction.

The instructive conclusion was: 1 under the vertical loading, the shear-lag effect was produced badly, more severer under concentrated loading than under uniform loading .2 the longitudinal bending deformation of the beam flange was true of the imitating plane assumption of deformation . 3 the width length ratio was confirmed as the first factor working on the shear-lag effect among all the geometric parameters;4 the shear-lag coefficient of simple-supported box-girder was severer than the continuous box-girder, the shear-lag effect in the inner supported section of continuous beam was much more severer, we need paying more attention for it in designing. 5 the non-liner characteristics of material deformation have littlie influence on shear-lag effect in BGCW. 6 the experiential calculating formulation and calculating diagram for the effective flange width was raised with the only factor of the width-span ratio., but the primary location of axis of bending moments should not be changed while calculating the inertial moment .

Based on the experiment data, the biomechanical performance indexes for stem-lodging resistance were studied and analyzed correlatively.

Under the assumption that the Earth is a triaxial rigid body which is rotating freely in the Euclidian space, the elliptic integral solution of the Euler dynamic equation is provided, and then the numerical solutions of the Euler dynamic as well as kinetic equation are realized.

The equations for the helicoid and cross section of a ballscrew are worked out and a numerical integral method for the computation of the moment of inertia of the cross section is proposed.

A speedy method of the Ichnography Geometry Quality Based On AUTOCAD Is introduced in this paper , A good method is provided for the Calculating of parameter such as center of shape , moments of inertia , product of inertia , and so on.

Based on the gray level co-occurrence matrix, moment of inertia, entropy, angle second moment of laser speckle, the texture of images is analyzed.

Assembly of the torsional spring constant and mass moment of inertia of each equivalent shaft-rotor element and the mass moment of inertia of each rotor yields the mathematical model of the entire shaft-rotor system.

The density of bone mineral substance and femoral geometry size and polar moment of inertia and torsional section modulus and rectangular moment of intertia and rectangular section modulus and biomechanics capabilities were determined.

Experimental Research on FBG Sensor for Large Curvature Detection;2. For large curvature arch, the neutral axis does not pass through the centroidal line of the cross-section, so the moment of inertia is not consistent with the second moment of area.

SUMO 之名起于 NIKE GOLF 几何杆头设计所创造出的超级(SUper)惯性矩 (MOment of Inertia);同时SUMO也是"相扑"的意思,刚好呼应它丰满的外型. 方形的几何力学达成高尔夫业界最大惯性力距SQ SUMO2不仅方形杆头在造型上独树一格,

polar moment of inertia：极惯性矩

θ 由上式所示,抗扭刚度就是抵抗扭矩的刚度.它不同于为了计算扭矩作用下的截面 剪应力所使用的极惯性矩(Polar Moment of Inertia).但是当截面形状是圆形或厚板 圆筒时,其抗扭刚度与极惯性矩相一致.
