A surface is formed when rotating a curve at the certain axis and finding the area of this surface is by using the formula {eq}S=2\pi \int_{a}^{b}y\sqrt{1+\left ( f'(y) \right )^{2}}dy {/eq} where {eq}\int_{a}^{b}\sqrt{...
Surface Area of the Solid of Revolution: The surface area {eq}S {/eq} of the solid of revolution that is generated when a curve say {eq}y=f(x) {/eq} is rotated about the x-axis is calculated as given below: {eq}S=2\...
Calculate the exact area of the surface obtained by rotating the curve about the {eq}x {/eq}-axis. {eq}x = 2 + 3y^2, \; 1 \leq y \leq 2 {/eq} The Area of Surface of Revolution: The area {eq}A {/eq} of...
Various strain amplitudes can be attained by altering the wire diameter and the radius of the curvature. Alternating strains are then applied by rotating the curved wire about its longitudinal axis as presented in Fig. 2. For the rotating-bending test setup shown in Fig. 2(a), the wire is...
The rotating anode (24) is formed from a section of a sphere. It can be made to tilt about a pivoting point (28) by a motor (26) and a spindle (27). The pivot is located at the centre of curvature of the surface of the anode (24). It also lies on the axis of rotation (...
Intersection Red X The point where a line, arc, or curve, intersects another line, arc, or curve On Shape Blue diamond A point on a shape On Line Red square A point along a line or curve On Axis Dashed line in the corresponding axis color (red or green) Alignment with one of the ...
The function of a rotating electrical machine is to convert mechanical power into electrical power, or vice versa. The conversion from mechanical to electrical power is made with a ‘a generator’ and the conversion of electrical to mechanical power with a ‘motor’. Electrical machines may be ...
about the y-axis The x y-coordinate plane is given. A curve and a shaded region are on the graph. The curve enters the window at the point(0,4),goes down and right becoming more steep and exits the window at the approximate point(1.3...
The surface area of the revolution depends on the curve equation and the interval of the rotation. There are two ways of defining the surface area of the revolution; one is about the x-axis and the second one is about the y-axis. Suppose you rotate...
