#### Question

The driving wheel of a gear system is of radius 1 cm and it has 8 teeth. For twelve rotations of

the driving wheel, if the driven wheel makes one rotation find :

(a) The radius, and

(b) the number of teeth in the driven wheel.

#### Solution

Given, radius of driving wheel ra = 1 cm

No. of teeth in the driving wheel Na= 8

Speed of rotation of driving wheel na = 12 rpm

Speed of rotation of driven wheel nb = 1 rpm

(a) Radius of driven wheel rb = ra× `"na"/"nb"` = `1xx12/1 =12 cm`

(b) No. of teeth in the driven wheel Nb = `Na xx (na )/(nb) = xx 12/1 = 96 `

Is there an error in this question or solution?

Solution The Driving Wheel of a Gear System is of Radius 1 Cm and It Has 8 Teeth. for Twelve Rotations of the Driving Wheel, If the Driven Wheel Makes One Rotation Find : (A) the Radius, and (B) the Number Concept: Concept of Machines Numercials.
