TL;DR
κ1,κ2,...,κn-1 is constant
What do we know of a curve(/what can it look like) in R^n if we know that κ1,κ2,...,κn-1 is constant?
 
Physics news on Phys.org
If you don't tell us what the ##\kappa##s are, not a lot.
 
Precisely the exercise asks: "Describe those curves of general type in R^n which have
constant curvatures."
 
So this is a homework type problem then. It should therefore be posted in the appropriate homework forum using the homework template - including the full problem statement, relevant equations, and your work/thoughts so far.

Indeed. @diffgeo4life - a little bit of Googling will get you at least part way there even if your textbook isn't helpful.

Sorry then, I guess then i will try posting in the Homework- Calculus and beyond forum, that looks most appropriate

Let u=u_i e_i be the displacement field of a continuum body. Then the displacement gradient tensor H based on classical formulation is given by H=grad u = u_{i,j} e_i \otimes e_j, where \otimes represents tensor product.H is decomposed intro two parts. Namely, H=epsilon+Omega. The infinitesimal strain tensor is given by epsilon=(H+H^t)/2, where H^t=transose(H). In component form, we have epsilon_{ij}=(u_{i,j}+u_{j,i})/2. On the other hand, Omega=(H-H^t)/2 describes the rigid body rotation...
