Course introduces analysis of forces acting on particles and rigid bodies in equilibrium. Force systems, centroids, and moments of inertia.

Homework: • • • • • •

Homework will be assigned each week, and typically will be due one week later. Individual homework, if you work in groups make sure to understand all problems Homework should be in standard engineering-pad The homework is a one unite week by week assignment it is not by chapter and should be submitted one time Use the face of the engineering pad only. One question per page

Important note • • • • • • • • •

This is a long material, a variety of subjects, and lots of homework. Read before you come to the class Understand and practice the examples in your book Each topic is built on previous topic If you get behind its almost impossible to catch up Work by yourself – if you work in group make sure you understand the material…. The best way to learn any material is teaching it ….. Explain problems to your group. The only way to learn the material is by solving problems. Attendance is strongly recommended. You cant learn engineering by yourself You need to be up to speed on vectors
