where 𝛼𝑦𝑡αyt represents the pressure angle of the involute (𝑒)(e) on the circle of radius 𝑟𝑦ry, as in Figure 6. Given that the gearing interaction between the profiles in any section perpendicular to the axes of the wheels mirrors that of two spur gears, it can be ass...
After calculating the arc radius R and curvature radius k of the tracking path, calculate the angular velocity w of the whole vehicle around the center of the tracking path according to the given tracking speed 𝑣𝑐vc of the whole vehicle, and then calculate the tracking speed and of the...

if you get any one of the area, the perimeter, the diameter, or the radius, you can figure out the rest. the formulas you need for circles, as they relate to perimeter (which on circles is called circumference ): area (circle) =π r ² diameter ( d ) = 2 r circumference : 2...
A circle through the origin can be parameterized by its radius R and the angle Φ, where the circle center is given by xc=RcosΦ, yc=RsinΦ. Such a circle touches the drift circle with center (x w, y w) and radius ρ if, and only if, the squared distance of the circle...
It remains to analyze Step 2 of the query procedure, where we need to find for a givenr_i \in \mathcal {O}^*({Q})allr_j\in \mathcal {O}such thatr_i\cap {Q}intersectsr_j. First notice that a rectangler_jintersects a rectangler'_i := r_i\cap Qif and only if (i) a...
The radius is known, and the area and perimeter are fairly simple functions of the length of side AB. Solving for the length of side AB is straightforward. The second method is probably a little simpler for this problem. The inscribed circle is tangent to each side of the triangle. The ...
