A tensile force of 15.000 N (15 kN} is applied to a 1-meter long hypothetical metal. Under this loading. the metal experiences a stress of 37.5 MPa, which is less than the material's yield strength. The metal has a square cross-sectional area. Calculate the edge length of the sample. Provide the answer in units of meters (m). A metal wire with an initial length of 250 mm and an initial diameter of 10 mm is subjected to a tensile load of 24.000 N (Le. 24 kN). Under this loading, the metal experienced an elongation of 0.369 mm. The metal only experienced elastic deformation under this loading. meaning once the load was removed the metal returned to its original shape and size. What material is this metal made from? Use the information provided in the question and the table i below to determine the material. 30:250mm;D0 =10111m:F= 24000N; Al=0.369m.m Modulus of Elasticity Yield Strength Tensile Strength (GPa) (MPa) [MPai Aluminum alloy Brass alloy 100 345 420 Copper 110 250 290 Steel alloy 207 450 550 0 Steel alloy 0 Copper 0 Brassalloy Aluminum alloy Compute the percent ionic character (%IC) of the interatomic bonds for the hypothetical compound AB.

The sealant is applied to the corners using a caulking gun, which is used to squeeze out the sealant material that typically consists of polydimethylsiloxane, curing agent, fillers, and additives. After hours of exposure to oxygen and moisture, the material solidifies into a flexible material that seals the gap. This is an example of what? O Chemical reaction that results in cross-linking of a thermoset polymer O Hardening through crystallization O Hardening of thermoplastics by reducing the glass transition temperatureSelect the sequence of events [in chronological order} that will take place if a forged piece of metal (a cold-worked metal) is exposed to temperatures above ~30% of its melting temperature. 0 Melting. recovery, recrystallization. followed by grain growth Recrystallization then recoverv. followed by grain growth 0 Recovery then recrystallization, followed by grain growth 0 Grain growth then recrystallization. followed by recovery
