The effective properties of the fiber-reinforced composite materials with fibers of circle cross section are investigated. The novel estimation for the effective coefficient of thermal conductivity refining the classical Maxwell formula is derived. The method of asymptotic homogenization is used. For an ...
Moreover, inserted profiled steel had an effect on ductility and shear capacity because of the increasing cross-section area of profiled steel and the composite action between profiled steel and concrete. A simplified formula for predicting shear capacity was proposed and predicted results were ...
, be simply multiplied with the cross-section area A = πR2 to obtain the flowrate Q. This average velocity is encountered fairly often because it makes the calculation significantly simpler. We will therefore shortly derive this velocity. The simplest derivation stems from the fact that the ...
Finding the volume of the region using the slicing method and note that the basic formula fot the volume is {eq}\displaystyle V=A\times l {/eq} where {eq}A {/eq} is the area of the cross-section and {eq}l {/eq} ...

The two copper wires have the same area of cross-section. What is the ratio of the magnetic inductions at the centres of the coils ? A2:1 B3:1 C4:1 D5:1Submit Two circular coils have diameters 10cm and 20cm with same number of turns. The ratio of the magnetic field induction ...
40) to the squared cross-sectional area A of the semi-circular canal; Ac the cross-sectional area of the cupula; and ν the kinematic viscosity of the endolymph (1·10−6 m²/s41). Equation 3 was used to estimate the sensitivity of canals with eccentricities of 0, 0.47, 0.71, ...
4. Circular measure • understand the definition of a radian, and use the relationship between radians and degrees; 2 • use the formulae s = rθ and A =r θ/2 in solving problems concerning the arc length and sector area of a circle. 1. The diagram shows the circular cross-...
Plastically denting a steel tube would obviously reduce the axial bearing capacity and bending strength of the tube due to the reduction of the effective section area and the growth of eccentricity. The details of plastic dent zones include two major aspects: the length of the plastic dent zone...
More specifically, it relates to a cellulose acetate fiber of which the cross section is non-circular, uniform in form and almost free of creases; multi-filaments thereof; a spinning dope for the production thereof; and a process for the production of the fibers. Prior Art A cellulose aceta...
