An impediment is anything that slows or blocks progress. It can refer to a physical thing, like a fallen tree in the road, or something more intangible, like how piracy is an impediment to the pleasure cruise industry in Somalia. See the pedi in there?
An oblique fracture is when the break has a curved or sloped pattern. A comminuted fracture is when the bone breaks into several pieces. A buckled fracture, also known as an impacted fracture, is one whose ends are driven into each other. This is commonly seen in arm fractures in children.
Compressive strength. In the study of strength of materials, the compressive strength is the capacity of a material or structure to withstand loads tending to reduce size. It can be measured by plotting applied force against deformation in a testing machine.ompresive strengh is a key value for design of structures. Compressive strength is often measured on a universal testing machine; these range from very small table top systems to ones with over 53 MN capacity. Measurements of compressive strength are affected by the specific test method and conditions of measurement.
