Two pulleys of diameters d1 and d2 and at distance x apart are connected by means of an open belt drive. The length of the belt is

A. π /2 (d<sub>1</sub> + d<sub>2</sub>) 2x + (d<sub>1</sub> + d<sub>2</sub>)<sup>2</sup>/4x
B. π /2 (d<sub>1</sub> – d<sub>2</sub>) 2x + (d<sub>1</sub> – d<sub>2</sub>)<sup>2</sup>/4x
C. π /2 (d<sub>1</sub> + d<sub>2</sub>) 2x + (d<sub>1</sub> – d<sub>2</sub>)<sup>2</sup>/4x
D. π /2 (d<sub>1</sub> – d<sub>2</sub>) 2x + (d<sub>1</sub> + d<sub>2</sub>)<sup>2</sup>/4x
Answer» D. ‚âà√¨‚àö√ë /2 (d<sub>1</sub> ‚Äö√Ñ√∂‚àö√ë‚àö¬® d<sub>2</sub>) 2x + (d<sub>1</sub> + d<sub>2</sub>)<sup>2</sup>/4x
