2. Belt problem - Wikipedia

   en.wikipedia.org/wiki/Belt_problem

   The belt problem. The belt problem is a mathematics problem which requires finding the length of a crossed belt that connects two circular pulleys with radius r 1 and r 2 whose centers are separated by a distance P. The solution of the belt problem requires trigonometry and the concepts of the bitangent line, the vertical angle, and congruent ...

3. Belt (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Belt_(mechanical)

   An automotive belt with the number "740K6" or "6K740" indicates a belt 74 inches (190 cm) in length, 6 ribs wide, with a rib pitch of 9 ⁄ 64 of an inch (3.6 mm) (a standard thickness for a K series automotive belt would be 4.5mm). A metric equivalent would be usually indicated by "6PK1880" whereby 6 refers to the number of ribs, PK refers to ...

4. Capstan equation - Wikipedia

   en.wikipedia.org/wiki/Capstan_equation

   The capstan equation [1] or belt friction equation, also known as Euler–Eytelwein formula [2] (after Leonhard Euler and Johann Albert Eytelwein), [3] relates the hold-force to the load-force if a flexible line is wound around a cylinder (a bollard, a winch or a capstan).

5. Belt friction - Wikipedia

   en.wikipedia.org/wiki/Belt_friction

   The equation used to model belt friction is, assuming the belt has no mass and its material is a fixed composition: [2] = where is the tension of the pulling side, is the tension of the resisting side, is the static friction coefficient, which has no units, and is the angle, in radians, formed by the first and last spots the belt touches the pulley, with the vertex at the center of the pulley.

7. Tractrix - Wikipedia

   en.wikipedia.org/wiki/Tractrix

   Tractrix with object initially at (4, 0). Suppose the object is placed at (a, 0) and the puller at the origin, so that a is the length of the pulling thread. (In the example shown to the right, the value of a is 4.)

8. Specific strength - Wikipedia

   en.wikipedia.org/wiki/Specific_strength

   The specific strength is a material's (or muscle's) strength (force per unit area at failure) divided by its density.It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio.

9. Sommerfeld number - Wikipedia

   en.wikipedia.org/wiki/Sommerfeld_number

   Nikolai Pavlovich Petrov's method of lubrication analysis, which assumes a concentric shaft and bearing, was the first to explain the phenomenon of bearing friction.This method, which ultimately produces the equation known as Petrov's law (or Petroff's law), is useful because it defines groups of relevant dimensionless parameters, and predicts a fairly accurate coefficient of friction, even ...
