Set up and solve static equilibrium conditions for objects in equilibrium in various physical situations. All examples in this chapter are planar problems. Accordingly, we use equilibrium conditions in the component form of Equation 12.7 to Equation 12.9.
Identify and analyze static equilibrium situations. Set up a free-body diagram for an extended object in static equilibrium. Set up and solve static equilibrium conditions for objects in equilibrium in various physical situations. All examples in this chapter are planar problems.
Explain how the conditions for equilibrium allow us to solve statics problems. We say that a rigid body is in equilibrium when both its linear and angular acceleration are zero relative to an inertial frame of reference.
In Physics, equilibrium is the state in which all the individual forces (and torques) exerted upon an object are balanced. This principle is applied to the analysis of objects in static equilibrium. Numerous examples are worked through on this Tutorial page.
The concept of equilibrium extends far beyond a simple physics problem. We encounter various forms of equilibrium: Mechanical Equilibrium: Balance of forces and torques (turning forces) Thermal Equilibrium: The heat flow is balanced, making both objects have equal temperature.
Solve the problem by applying either or both of the conditions for equilibrium (represented by the equations \(net \, F = 0\) and \(net \, \tau = 0 \), depending on the list of known and unknown factors.
Equilibrium and Center of Gravity in Real Objects. Before applying the concept of vector sums to matters involving equilibrium, it is first necessary to clarify the nature of equilibrium itself—what it is and what it is not.
