- 1. Equilibrium
- 2. Equilibrium <ul><li>Equilibrium is a state of balance or the state of motion of an object is not changing. </li></ul><ul><li>Static Equilibrium </li></ul><ul><li>When a state of rest is maintained by the object </li></ul><ul><li>Dynamic Equilibrium </li></ul><ul><li>When a state of constant nonzero velocity is maintained </li></ul>
- 3. Forces A force is any influence that causes a free body to undergo an acceleration. Force can also be described as a push or pull that can cause an object with mass to accelerate, or deform. A force has both magnitude and direction, making it a VECTOR quantity.
- 4. Concurrent and Non Concurrent Forces Concurrent Force Non-Concurrent Force
- 5. Condition of Equilibrium <ul><li>For an object to be in translational equilibrium, the vector sum of all forces acting on the object must be zero. </li></ul><ul><li>(acceleration is zero) </li></ul>
- 6. Sample Problem 1: <ul><li>A mirrored sphere weighing 200 N is suspended from the ceiling of a ballroom by two cables, as shown in the figure. What is the tension in each of these cables? </li></ul>
- 7. Sample Problem 2: <ul><li>Calculate the tension in the tie rope when the weight of the tree stump is 800 N. </li></ul>
- 8. Seatwork: Calculate the tension in the tire rope Calculate the tension in cable and the inward force the boom exert on the wall
- 9. Assignment: Find the tension in the cable from the top of the mast to the top of the boom
- 10. Questions:
- 11. For next meeting: <ul><li>Define the following: </li></ul><ul><li>Moment arm </li></ul><ul><li>Center of Gravity </li></ul><ul><li>Torque </li></ul><ul><li>Fulcrum </li></ul><ul><li>Sense of rotation </li></ul><ul><li>Pivot </li></ul>
- 12. Reference: <ul><li>Physics for Scientists and Engineers with modern Physics 7 th Edition by Jewett/Serway © 2008 Thompson Learning Inc. </li></ul>
