Learners examine how a force may be considered to act at any point along its line of action as long as the magnitude and direction of the force remain unchanged. Numerical verification is provided.
Weight-Volume Relationships: Introduction to a 3-Phase Diagram
In this animated activity, students read about weight-volume relationships within a given sample of soil or aggregate. They complete problems using a 3-phase diagram.
Students view photos of an electric pencil sharpener as it is disassembled. The learning object is intended to prepare students to be able to identify the components and create an assembly process in a future activity.
