Question

Quizplus · Accepted Answer

The intrados is the term used to describe the concave curve that bounds the entire curvature of the lower limits of an arch. A beam refers to a structural element that is capable of withstanding a load primarily through bending. A supporting load refers to the force that is applied to a structure to keep it in place. A compressive load refers to a force that tends to shorten or squeeze a material.
