# Gear

Two gears, fit into each other, has transfer 2:3. Centres of gears are spaced 82 cm. What are the radii of the gears?

Result

r1 =  49.2 cm
r2 =  32.8 cm

#### Solution:

$r_1 = \dfrac{ 82 }{ ( \dfrac{ 2}{ 3} +1 ) } = 49.2 \ \text{ cm }$
$r_2 = \dfrac{ 2}{ 3} r_1 = 32.8 \ \text{ cm }$ Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
