“Carbyne’s tensile strength — the ability to withstand stretching ....”
That’s an overly-simplified statement. The tensile strength of a material is the maximum amount of tensile stress (pulling force) it can withstand before failure. Some materials are ductile (stretch under tension), others are brittle (don’t stretch before breaking). A ductile material may have the same tensile strength as a brittle material — it would just stretch a lot more before failure. I won’t mention modulus of elasticity.
The writer is but an ignorati...... trying to enlighten others ofhis ilk.
He also thinks concrete is cement
