CAS PY 105 Chapter Notes - Chapter 12: Momentum, Bulk Modulus, Stress (Mechanics)
Document Summary
When the the linear and angular momenta are equal to zero, then this special case is called static equilibrium, and there is no movement of any kind, in the reference frame from which they are being observed. Learning objectives: explain what an indeterminate situation is, for tension and compression, apply the equation that relates stress to strain and. Like the nail, all rigid bodies are to some extent elastic, which means that we can change their dimensions slightly by pulling, pushing, twisting, or compressing them. There are three ways in which a solid might change its dimensions when forces act on it. An object can undergo tensile stress, to stretch by an amount l. An object can undergo shear stress causing it to deform by an amount x. Lastly, an object can be compressed, to shrink by an amount v .
