    How Do You Calculate Probability Distributions for Measured Fibre Angles?

    Yes, that's what I thought, thanks for your help, maybe it can be moved?

    How Do You Calculate Probability Distributions for Measured Fibre Angles?

    I know it does, what I'm asking is how was it obtained in the first place? Would you just add up the number of fibres between a certain angle and then divide by the total number of fibres? And that gives probability?

    How Do You Calculate Probability Distributions for Measured Fibre Angles?

    I'm asking how would generate the probabilities on the Y-axis?

    How Do You Calculate Probability Distributions for Measured Fibre Angles?

    This could go in the homework section I suppose, but I couldn't follow the guidelines, so I'll try asking it here. The attached image is a probability distribution for measured fibre angles from a spray up carbon fibre process. This is in a report that I need to explain. To get the...

    Graduate How Do You Calculate the Length of a Curved Fibre in Composite Processes?

    Actually what I meant to say is that I want to calculate the fibre length or arc length, and I know the chord length.

    Graduate How Do You Calculate the Length of a Curved Fibre in Composite Processes?

    Sorry, I realize having sat down and worked through the problem that I was being very stupid :rolleyes:, and to work out what r is is obvious :smile: what nomather1471 posted applies to all fibre lengths

    Graduate How Do You Calculate the Length of a Curved Fibre in Composite Processes?

    I need to calculate the the arc length for different fibre lengths and offsets, so I always have the fibre length and offset.

    Graduate How Do You Calculate the Length of a Curved Fibre in Composite Processes?

    Thanks zgozvrm, I have that now. I just need to work out what the radius would be for different fibre lengths, nomather1471 how did you get that diagram?

    Graduate How Do You Calculate the Length of a Curved Fibre in Composite Processes?

    and that doesn't give me the values between the two points of the line (or fibre in this case)

    Graduate How Do You Calculate the Length of a Curved Fibre in Composite Processes?

    OK, what if I want to change the values of 4 and 200, how did you work that out?

    Graduate How Do You Calculate the Length of a Curved Fibre in Composite Processes?

    Here is an image which will hopefully make the problem clearer

    Graduate How Do You Calculate the Length of a Curved Fibre in Composite Processes?

    This is PhD level work, and mathematics isn't really my thing, so thank you so much in advance if you can help me! I am trying to find the length of a curved fibre for a composites process I am working on. The fibre geometry is as follows: The length between 2 points is 200mm, but the fibre is...

    Graduate Can the integral of cos^-1(arctan) be evaluated directly?

    yes, that is right, and a and b can be any numbers really, as they define the shape of the sine wave.

    Graduate Can the integral of cos^-1(arctan) be evaluated directly?

    so you would need a ( in front of the integral sign to complete it

    Graduate Can the integral of cos^-1(arctan) be evaluated directly?

    That is correct, and the whole integral is ^-1.
