2.1.7 Calculating Truss Forces
This week in engineering we had a short week. We worked on the calculating truss forces worksheet. We are to calculate the static determinacy with 2J=M+R. The J = for number of joints. M=number of members and R=number of reactions within a support. With these components we are able to calculate the static determinacy of an object.

Sea Perch Preparation
This week in class we finished our Sea Perch project! On Monday we finalized our sub with our teams. On the block day and Thursday we prepares for the Sea Perch games. We made weights, buoys, and riddles. On Friday we races our subs and participated in a variety of different games.
Trusses
This week in engineering we tackled Trusses. On Monday we had a lecture about trusses. On Wednesday we worked on the "Trusses" packet. The packet reinforced our understanding about trusses using angles, sin and cos.
