Fishing rod

by gonzalo

Jan 31, 2011

Hi,

 

Im trying to make a fishing rod, a flexible line that bends when you put some weight at the end.

 

I have read the basic kangaroo manual but I need more information about rods to develope this definition.

 

My problem is that when I fix just one anchor point the rod falls down to the floor, so it looks like I should be fixing another anchor point, but how??

 

any help would be appreciated.

 

Thanks in advance

    I've attached a fixed version of the file.

     

    To fix the angle of the rod at one end you need to anchor 2 consecutive points. (the 0th and 1st)

     

    Also, the bending force does not automatically include length preservation, so you need to add some springs for that too.

      Hi, I'm a student from Portland State University, I have been following "Rod discussion", I think that the following link may help you with your understanding of the Fishing Rods, Graig Spolek is a Mechanical Engineering Professor at PSU, and has written a fair amount of fishing poles.  See link below.
