what is r(x)? what is x?  what is X?  what is ra? what is rb?  Is L the length of the bar = 150mm


<div>
r(x) is the radious equation of x<br />
ra = the radious at the left side = 10mm<br />
rb = radious at right side = 5 mm<br />
L = lengh<br />

</div>


r(x) is the radious equation of x
ra = the radious at the left side = 10mm
rb = radious at right side = 5 mm
L = lengh


<div>
is r(x) the radius of the bar in meters at x mm from the left end?
</div>


is r(x) the radius of the bar in meters at x mm from the left end?

<div>
<div class="content wysiwyg-content">
I have a bar that the radius varies linearly from 10mm to its left end to 5mm at the right end,<br />
The length of the bar is 150mm<br />
I am trying to build the r(x) linear equation.<br />
<br />
can i do <br />
<br />
r(x) = ra + ( rb-ra) X/L &nbsp;= 0.01 - 0.005 * &nbsp;X/L<br />
<br />
is this correct ? <br />
