WebDiameter: the longest distance from one end of a circle to the other. The diameter = 2 × radius (d = 2r). ... If the length of an arc is $\theta$ degrees or radians then the … WebApr 14, 2024 · A right triangle with two sides formed from the radii of a circle and the third side tangent to the circle. As long as the angle \theta θ is sufficiently small, the length of s s ( ( the arc subtended by \theta) θ) is very close to that of s^ {\prime} s′, the third side of the triangle. The small-angle approximation thus corresponds to s ...

WebApr 5, 2024 · Here as mentioned $\theta $ is the parallax angle, b is the distance between two points of separation, D is the distance of source from any point of observation. We know that $\theta $ is a very small angle. So the value of tan $\theta $ will be very less as well. Therefore there will not be much difference between tan$\theta $ and $\theta $. WebStress Concentration Factor, \(K_t\) The Stress Concentration Factor, \(K_t\), is the ratio of maximum stress at a hole, fillet, or notch, (but not a crack) to the remote stress. For our case of a hole in an infinite plate, \(K_t = 3.\) Do not confuse the Stress Concentration Factor here with the Stress Intensity Factor used in crack analyses. black owned brunch spots in brooklyn
