PROBLEM SOLVING TACTICS

PROBLEM SOLVING TACTIC

Here is a list of steps for solving static equilibrium problems:

1. Draw a sketch of the problem.

2. Select the system to which you will apply the laws of equilibrium. drawing a closed curve around it on your sketch to fix it clearly in your mind.

3. Draw e free-body diagram of the system. Show all the forces that act on the system, labeling them and making sure that their points of application and lines of action are correctly shown.

4. Draw in the x and y axes of a coordinate system.

5. Write the two balance of forces equations. using symbols throughout.

6. Choose one or more rotation axes perpendicular to the plane of the figure and write the balance of torques equation for each axis. If you choose an axis that passes through the line of action.
