plane elasticity in polar coordinates - polar coordinate use, in problems involving boundaries formed by circular arcs or radially straight linescompatibility equation - for plane elasticity in terms of polar coordinatesactive stress significance - differences, living biological tissues and lifeless materials...
curved beams of rectangular section with a circular axis etc., it is advantageous to use in polar coordinates instead of rectangular coordinates. The position of a point P in coordinates is defined by the radial coordinate r and the angular coordinate , as show in Fig.: x y o r dr r r...

Sketch the region in the plane consisting of points whose polar coordinates satisfy the given conditions. r≥ 1 相关知识点: 试题来源: 解析 The curve r=1 represents a circle with center O and radius 1. So r≥ 1 represents the region on or outside the circle. Note that θ can take on...
Integral calculus is used to find plane areas in rectangular coordinates by finding the integral of a function that represents the boundary of the shape. This integral represents the area under the curve and can be evaluated to determine the exact area of the shape....
Use polar coordinates to find the volume of the region bounded by the plane {eq}z = 25 {/eq} and the paraboloid {eq}z = x^2+y^2 {/eq}. Double Integrals in Polar Coordinates: Some double integrals have circular symmetry around the origin, and thu...
1) plane polar coordinates 平面极坐标 1. The motion of a simple pendulum with varying length coupled with a vertical motion is investigated,the second-order differential equation set of the motion is obtained in terms of plane polar coordinates. 研究了一个变摆长单摆运动的例子,在平面极坐标系...
