Deflection of a Center-Loaded Rectangular Beam
Experiment #1 from Materials Testing: Beams to Bridges with Go Direct® Structures & Materials Tester
Introduction
Imagine you are walking across a simple plank that spans a creek and you stop in the middle of the plank to enjoy the scenery. Consider the plank you are standing on. You will notice it is bowing a bit downward where you stand. If you were to change the dimensions, could you make the beam less flexible (more rigid)?
Objectives
- Students will engage in an inquiry activity to develop a mathematical model based on observations (of their own devising) of the physical world.
- Students will understand the factors that affect the deflection of a center-loaded rectangular beam, supported on both ends, including width, thickness, and length.
- Students will construct a model representing the relationship of factors affecting the deflection of center-loaded rectangular beams.
Sensors and Equipment
This experiment features the following sensors and equipment. Additional equipment may be required.
