Homework Statement
A body which in the reference configuration is a unit cube with its edges parallel to the coordinate axes undergoes the following deformation:
x1=a1(X1+sX2), x2=a2X2, and x3=a3X3
(where a1,a2,a3,s are constants).
determine the lengths of its edges after the deformation
Homework Equations
The Attempt at a Solution
I think i need to know the x1, x2, and x3 before the deformation, as in when it was a unit cube. so if x1=1 then the new length (length after deformation) will be:
sqrt[(1-a1(X1+sX2))^2]
but this is not working for me since the answer is:
lengths: a1, sqrt[(s^2)(a1^2)+a2^2], a3
