Free Body Diagrams Practice your skill at constructing free-body
diagrams for a given physical situation. Twelve different
descriptions of a physical situation are presented; your goal is
to determine the type and relative magnitude of the forces
acting upon the described object. - Use the pull-down menus on
the right side of the screen to identify the types of forces
acting in the rightward, leftward, upward and downward
directions. - Use the pull-down menus to identify the relative
magnitude of each individual force. The important factor is not
whether you indicate Large, Medium or Small, but rather that you
indicate whether the rightward force is larger, smaller or of
the same magnitude as the rightward force. - When you have
identified the type and relative magnitude of all applicable
forces, click on the Check Answer button at the bottom of the
screen. - Repeat steps 1-3 until you have successfully answered
all twelve problems. - If necessary, use the Try New Problem
button to skip the given problem; you
