PT2: Classwork for Monday feb.7

Force Transducers: Stress vs Strain 1. Read pp.23-27 2. Answer the following on lined paper: What is elasticity? What is the difference between compression and tension forces? Draw a representation of each. List the other 3 types of forces that can act on objects. Draw a representation of each. What is Young’s Modulus used for? What is stress? What is the formula and units for stress? What is strain? What is the formula and units for strain? How is “Young’s Modulus” defined? It’s formula and meaning of each variable? Do all materials have the same modulus value? Give an example. Sketch a typical stress-strain curve and label each key characteristic? Define elastic limit and point of failure. What is a strain gauge? What is Hooke’s Law and how is it related to strain gauges? Identify 4 types of strain gauges.

Force Transducers: Stress vs Strain continued 3. Read pg.9 in workbook 4. On the back of your activity page from Friday make notes on key concepts including the Resistivity formula,Figure 11-11, and example 11-A 5. Complete Q1-3, 5-7 on pg.15. Use GFS for Q#6
