<p>In general, a force does work when it produces a displacement along its line of action. When we talk about virtual work, we're imagining those displacements becoming infinitesimally small. </p>
<p>This page covers systems of connected rigid bodies with 1 degree of freedom (DOF). That is, the system's entire configuration can be described using one independent coordinate, oftentimes a single angle, <InlineEquation equation = "\\theta."/> In general, a force does work when it produces a displacement along its line of action. When we talk about virtual work, we're imagining those displacements becoming infinitesimally small. </p>

<p> Work is defined as <strong>positive</strong> when the force and the displacement are in the same direction, and <strong>negative</strong> when the force and displacement are in opposite directions. </p>
