Correct Answer
(A) $$pi left( {{{ ext{r}}_1} + {{ ext{r}}_2}}
ight) + frac{{{{left( {{{ ext{r}}_1} + {{ ext{r}}_2}}
ight)}^2}}}{{ ext{x}}} + 2{ ext{x}}$$
[#113] Two pulleys of radii r 1 and r 2 and at distance x apart are connected by means of an open belt drive. The length of the belt is
Correct Answer
(B) $$pi left( {{{ ext{r}}_1} + {{ ext{r}}_2}}
ight) + frac{{{{left( {{{ ext{r}}_1} - {{ ext{r}}_2}}
ight)}^2}}}{{ ext{x}}} + 2{ ext{x}}$$
