Have a nice week off!

Wednesday, 2/3/10

Today in class we will be doing a forces lab on PBS.com.


You will be exploring different actions that occur in structures.  On a piece of binder paper, keep track of the forces that occur in each action. Draw diagrams of the forces in each action and write down examples of where the action takes place in a real structure.

Answer the following questions after you have taken notes on the forces in 5 different actions.


1.  Are the forces balanced forces or unbalanced forces in each action.


2.  Why do you think it is important for engineers to know what forces happen in each action?


3.  If you were an engineer asked to build a new bridge, what actions from this lab would you need to keep in mind when designing the bridge?  Explain why you chose the actions.


HW:  Page 94 #1-6
