In tensile and shear loads on concrete, which aspect is primarily concerned with stretching?

The aspect primarily concerned with stretching in the context of loads on concrete is tensile load. Tensile loads refer to forces that attempt to pull or stretch a material apart. In concrete, tensile stress occurs when the material is subjected to forces that pull it away from itself, creating a stretching effect. Concrete is relatively strong in compression, which means it can withstand being pushed together, but it is much weaker in tension and can easily crack or fail when pulled apart. Understanding tensile loads is crucial for designing structures to ensure they can withstand various forces without experiencing failure.
