Here is what I learned during our study of Structures and Mechanisms.

Here is one of the structures that are group made in class. we placed 3rd in the compation with are bridge holding a mas of 750kg. Are group found out that nothing underneath are bridge did not help it.

This is our group's popcicle stick house. When we applyed force on the top of our house we found out that the little stick underneath the roof supported the house's walls from pointing out the side. Our groups found ocut that when we put the wall underneath the little stick right on top that it would help support the house from the walls pointing out.

media type="custom" key="21590906" Pucks in the eirlier days were made out of wood but if the people could not find wood they would use a stone. Now days people make pucks out of rubber. Rubber is made of a para trees sap so you can keep making rubber with para trees. Para trees are from a whole bunch of places in the world.

=Production= Pucks are made out of natural rubber and two types of oil that make the puck durable and certain minerals act like curing agents and a form of cold dust called carbon blacks serves us the filler. Workers put the ingredients in a polimanary mixer the workers start with putting the slabs of natural rubber then anti oxidents to lengthen the rubbers life span then one type of oil to help blend in the dry chemicals then another type to refine it then additives such as calcium carbodate to help cure the rubber during the molding process and finally the carbon black filler. Then they put the ingredients on a roller machine then they put on a big chunk of rubber then the ingredients rub on the chunk of rubber then they put the chunk of rubber in a molding tray. And then they bring the chunks of rubber into a company lab technicians evaluate the quality of the rubber. Then it is poured into a machine that makes long tubes of rubber, the same diameter as a puck. Finally a machine slices each tube into 1.1 inch sections. These rubber discs are put into a compression machine in a tray that looks like a muffin pan. The tray goes into a curing machine that cooks them at 300 degrees Farenheit for 18 minutes. Pucks are rock hard when they come out. They cool for 24 hours.

The edges of the puck get dimpled from the curing tray. The rough edges create friction between the hockey stick and the puck. This gives players like me greater control and a better shot.
