Well, the idea with the OP was a rough spherical shape. A perfect ball shape is obviously an unrealistic expectation. Besides, that part isn't so much strength as it is precision and dexterity anyway, and the question is about strength.

Remember that compresing a side results in the other sides expanding. That's why I said it is deforming, isn't like the whole cube is being compressed.
If you add a compressive force to a cross section, the perpendicular cross section receives a tensile force.
Example:
If you fill a ballon with water and squeeze it, the ballon will deform. You know that water cannot be compressed. Samething happens with the Titanium block, it is deforming not compressing.
Wrong! Stop making up Pseudo science.
Compression tests always results in the cross sectional area getter larger, but no pulling forces are acting. It takes about twice the force to compress titanium than to pull it apart. They are NOT EQUALS. To test tensile strength, a thin strip of the material is pulled with an increasing force until it elongates and snaps. Then the final force is divided by the strip's cross sectional area to find the tensile strength
And matter can be compressed to reduce its total volume and increase its density, even water.
Never let anyone else define you. Don't be a jerk just to be a jerk, but if you are expressing your true inner feelings and beliefs, or at least trying to express that inner child, and everyone gets pissed off about it, never NEVER apologize for it. Let them think what they want, let them define you in their narrow little minds while they suppress every last piece of them just to keep a friend that never liked them for themselves in the first place.
