Question

The driving wheel of a gear system is of radius $1cm$ and it has $8$ teeth. Given gear ratio is equal to 12, the number of teeth in the driven wheel is

• A. $55$
• B. $8$
• C. $96$
• D. $90$

Answer 1

The correct option is C $96$

Gear ratio = T2/T1, where T2 is the "input gear" (also known as drive gear) transmits power to the "output gear(T1)" (also known as driven gear)

$12=X/8$

$X=96$

Answer (C) 96
