Force length relationship - Study guides, Class notes & Summaries

Solid Mechanics 2 Marks Question with Answers UNIT -1 1. Define stress. When an external force acts on a body, it undergoes deformation. At the same time the body resists deformation. The magnitude of the resisting force is numerically equal to the applied force. This internal resisting force per unit area is called stress. Stress = Force/Area 2. Define strain When a body is subjected to an external force, there is some change of dimension in the body. Numerically the strain ...

A nurse is discussINg the pressure generated at the end of diastole. Which term is the nurse describINg? Preload Afterload Systemic vascular resistance Total peripheral resistance ANSWERS A Preload, not afterload, is the volume and associated pressure generated IN the ventricle at the end of diastole. Afterload is the resistance to ejection of blood from the left ventricle. Systemic vascular resistance is related to afterload. Total peripheral resistance INcreases afterload. R...
