Which outcome during Inca stone masonry increases when internal friction is at its maximum limit?

💡 Explanation

Seismic collapse increases, because at maximum internal friction the stone blocks are immovably locked; therefore seismic shear forces exceed material limits when subjected to ground motion, rather than dissipating force through block movement.
