Not sure what you mean by the context. Let's say you want to design the wall to withstand the force but you know the force felt by the wall will be reduced due to existence of the mass of soil.
Hello,
Please see the attached sketch. A car hits a mass of soil and applies the impact force of F. The force/wave travels the distance L through the mass at the end of which there is a wall so I think the force attenuates. Assume we have all the properties of the mass. My question is, what...
Hello everyone,
So let's say we have a cuboid.
On the X axis, it's divided to 4 segments (i.e. by 3 lines parallel to z axis) (segx=4).
On the Y axis, it's divided to 3 segments (i.e. by 2 lines parallel to z axis) (segy=3).
On the Z axis, it's divided to 8 segments (i.e. by 7 lines parallel...

Thanks for the response but I guess what you refer to requires using indices and Einstein Summation stuff .. I'm only supposed to use the definitions ... Maybe my formula Sij=Sji was misleading or maybe it was not...
Could you be a little more specific please? Does that coordinate independent...
Homework Statement
Prove that symmetric and antisymmetric matrices remain symmetric and antisymmetric, respectively, under any orthogonal coordinate transformation (orthogonal change of basis):
Directly using the definitions of symmetric and antisymmetric matrices and using the orthogonal...
