Problem Solving and Measurement Concepts

The video tutorial covers the setup of activity 2.3.1, focusing on stress-strain calculations using the GUESS method. It includes two problems: calculating stress exerted by a base plate on a concrete slab and determining the maximum load a steel rod can support. The tutorial follows a structured problem-solving approach, similar to PLTW's five-step method, with variations.
