Your boss is convinced and decided that the customers will save a lot of energy in processing material if the molecular weight of the polymethyl methacrylate (PMMA) manufactured is lower from 250,000 g/mol to 150,000 g/mol. As a chief engineer in charge of mechanical properties, how will this affect the fracture energy (area under the stress strain curve)? Do you agree with this decision?

Question

Your boss is convinced and decided that the customers will save a lot of energy in processing material if
the molecular weight of the polymethyl methacrylate (PMMA) manufactured is lower from 250,000
g/mol to 150,000 g/mol. As a chief engineer in charge of mechanical properties, how will this affect the
fracture energy (area under the stress strain curve)? Do you agree with this decision?
