Final answer:
Concrete is a ductile material that is commonly used in residential and small commercial buildings. It can withstand compression but is weak against shear forces.
Step-by-step explanation:
Concrete is a ductile material that has marginal resistance to forces compared to its weight, but it does the job for most residential and small commercial buildings. Concrete used in buildings can withstand compression, such as in pillars and arches, but it is not very strong against shear, as might be encountered in heavily loaded floors or during earthquakes.
