Week 1 Lecture Notes ME 214 Vector Statics Lecture 1, Chapter 1 Instructor: A Rezaei Students will be able to: a) Identify what is mechanics / statics. b) Work with two types of units. c) Round the final answer appropriately. d) Apply problem solving strategies. WHAT IS MECHANICS? Study of what happens to a “thing” (the technical name is “BODY ”) when FORCES are applied to it. BRANCHES OF MECHANICS UNIT SYSTEMS Force, mass and acceleration are called the base units. The fourth unit, time is derived from the acceleration term. We will work with two unit systems in statics: International System (SI) U.S. Customary (USCS) PROBLEM SOLVING STRATEGY: IPE, A 3 Step Approach 1. Interpret: Read carefully and determine what is given and what is to be found / delivered. Ask , if not clear. If necessary, make assumptions and indicate them. 2. Plan: Think about major steps (or a road map) that you will take to solve a given problem. Think of alternative/creative solutions and choose the best one.
