Read MoreA.) TRUE. B.) FALSE. Get the Correct ANSWER. TRUE. Explanation: Especially, cars are intended to crush and consume some of the collision. However, they cant crumple too enough or our legs will get crushed also, which is not good. Its all based on the postulate that the force of the collision is less if the entire deceleration takes place over a ...

Recognize broad groupings of complications of fractures.
Read MoreThe material enters the roll crusher machine and is impacted by the roll as it rotates. Then, as the material is pulled between a crushing plate or rolls, shear and compression forces act upon the material.A combination of impact, shear, and compression are the forces necessary to perform the crushing and size reduction in a Williams roll crusher.
Read MoreDeaths resulting from blunt force trauma are some of the most common cases encountered by the practicing forensic pathologist. Whereas other forms of traumatic death (eg, gunshot wounds, sharp force injuries) occur under a relatively limited number of circumstances, deaths resulting from blunt force trauma occur in a variety of scenarios.
Read MoreA special pattern of bilateral skull fracture can occur when there are crushing forces applied against the infant skull. Skull fractures cannot occur without impact of the head against a rigid object. They cannot occur with shaking. Skull fractures are caused by a deformation of the skull due to impact of some kind.
Read MoreA large, crushing force applied to a sizable area over several minutes will result in vast tissue damage; for example, failure of the integrity of a retaining wall at a construction site will likely cause significant blunt impact injury if the wall collapses on and traps the legs of an individual.
Read MoreIn addition to the use of purchased tools, seven of the implements used in the present research were created and designed to imitate the size and impact angle of other surfaces possibly found in hacking and blunt force trauma. A hacking machine was used to inflict trauma on the long bones at a consistent, controlled level of force.

Read MoreFor in-plane impact, the energy absorption ability of skeletal structures is mostly dependent on the dynamic crushing strength or the plateau stress (plateau region on the stress-strain curve during impact/compression process), and thus the theoretical analysis of plateau stress is discussed in this study.
Read MoreA break at the point of impact is referred to as direct trauma injury and results in transverse, penetrating, comminu- ted, or crush fractures (Fig. 11.2). For example, crush fractures result from direct force to cancel- lous bone, which collapses, such as when an object is dropped on the hand or foot.

Read MoreBecause force is a component of work and an impact is the conversion of energy into work, you can use the equations for energy and work to solve for the force of an impact. The distance traveled when the work is accomplished by an impact is called the stop distance. It is the distance traveled by the moving object after the impact has occurred.
