A nanomaterial’s strength increases by 12% for every 10 nm decrease in thickness down to 30 nm. If it has a strength of 250 MPa at 100 nm thickness, what is its strength at 40 nm?

How a Nanomaterial’s Strength Improves: A 12% Gain Every 10 nm Reduction in Thickness In the rapidly advancing field of nanotechnology, even subtle changes in material thickness can significantly influence mechanical properties—particularly strength. A compelling example lies in a class of high-performance nanomaterials where structural optimization demonstrates a remarkable trend: strength increases by 12% for every 10 nm reduction in thickness down to a critical threshold of 30 nm. This phenomenon opens new pathways in engineering ultra-strong, lightweight materials used in aerospace, electronics, and biomedical devices. ### Strength Growth Across Thickness: The 12–40 nm Case
