Hi

I have to use the find function to find A but no matter how i change the Dp1 The A remains the same at the end , but if i change the Ainitial A takes value of Ainitial

"I have to use the find function":

Who is forcing you to use the Find function?

If you want to find the value of A that satisfies your equation, making f(A)=0, there are several options in Prime.

One of them is to use a solve block, in which you CAN use the Find function. Conversely if you HAVE to use the Find function you also HAVE to use a solve block, because the Find function can ONLY be used in a solve block.

From your picture (it's much better to attach the Prime worksheet if you need help) it seems that you have not set up a solve block, so the Find function in your sheet does not work like you might have thought it would.

I suggest you look up the usage of a solve block in the help system of Prime. There are excellent examples to help you.

Success!

Incidentally, there are two values for A that solve the equation:

The EXACT solution is found with:

Given your numeric values, these are approximated with:

A=0.263 mm, or A=759.406 mm

Hi , our teacher used the find function in this case since we need to find the exact center distance of a belt drive,

I've also set up a solve block ,as you can see in the screenshot

It's probably on my part that the function is not working normally . (changing Dp1 should affect value of A) , also i've written the function just like my teacher did he is also using a older version of mathcad ( mathcad 15)
