 # Finding The Length Of A Belt Around Two Pulleys

belt problem - wikipedia,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 angles.pulley geometry exercise,b = length of belt between tangent point on two pulleys = √l2 − (r− r)2 l 2 - ( r - r) 2. l = the separation distance between the two circle's centers. because of the geometry we are defining as a belt wrapped around two circles, the line segment , b, touches both circles at a tangent point..
