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 Equilibrium Concept Builder includes 36 questions organized into 12 Question Groups and spread across three difficulty levels. Each question involves the same task - add an east-west vector and a north-south vector to an object so that it is in a state of equilibrium.
This example shows that when solving static equilibrium problems, we are free to choose the pivot location. For different choices of the pivot point we have different sets of equilibrium conditions to solve.
When all the forces that act upon an object are balanced, then the object is said to be in a state of equilibrium. The forces are considered to be balanced if the rightward forces are balanced by the leftward forces and the upward forces are balanced by the downward forces.
PHYSICS 12 ROTATIONAL EQUILIBRIUM WORKSHEET 1 1. For the following diagrams, determine the perpendicular component F⊥⊥⊥⊥ for each force shown, as well as its torque, relative to pivot P: a) 60 ° b) Fcable = 570 N; find F ⊥⊥⊥⊥ 0.730 m and torque 25 °
10 Μαΐ 2013 · 1. What is the definition of equilibrium? Can an object be moving and still be in equilibrium? Explain. 2. For this lab, what criteria will you use to decide when the forces acting on the ring are in equilibrium? 3. Draw a set of three vectors whose sum is zero. 4. How will you estimate the uncertainty of each force acting on the ring? 5.
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.
