## Homework Statement

Consider a gear set with the following attributes:

• A pinion base radius of 11mm

• A centre distance of 73mm

• A pressure angle of 24 degrees

• A module of 5.8mm

What is the maximum addendum radius (mm) that the pinion can have to avoid interference?

## Homework Equations

r

_{a}max=√r

_{b}

^{2}+c

^{2}*sin(θ)

^{2}

r

_{a}max= maximum noninterfering addendum circle radius of pinion gear

r

_{b}= base circle radius of the same member

c= center distance

θ=pressure angle

## The Attempt at a Solution

r

_{a}max=√r

_{b}

^{2}+c

^{2}*sin(θ)

^{2}

r

_{a}max=√0.011

^{2}+0.073

^{2}*sin(24)

^{2}

r

_{a}max= 0.0316mm

So that is the answer that I got but I was not sure if you need to use the module for anything or whether it is just extra info

cheers
