Product Summary
Consumable replacement parts for Cast Beams. These can also be used with the Advanced Structures Set.
The Cast Beam Spares Set consists of beams that are models of the reinforcement bars (“rebar”) used in construction, and molds that are used to produce a model of a beam of reinforced “concrete” or prestressed “concrete”. A mixture of fine sand, plaster, and water is poured into the assembled rebar beam and mold. After the mixture hardens and the mold is removed, the beam can be used as a #4 beam (17 cm) in any PASCO Structure Set.
Sensors and weights can be used to measure the strength of the cast beam when it is a component of a PASCO Structure.
Features
- Easily connect to other structures pieces
- Test using Stress/Strain Apparatus
- Easy instructions for molding pre-tensioned and reinforced beams
How It Works
Use plaster to mold beams from this rebar and case set; the molded pieces have normal Structures System ends that fit into any connectors and thin plastic rods that act like rebar in the cast beam. Students can build and test both reinforced and pre-tensioned beams in larger bridge structures and substitute these beams for any I-beam.

Product Guides & Articles
PASCO Structures System
PASCO’s Structures System offers realistic, hands-on tools for students to design and create life-like structures in the classroom. Intended for teaching principles of engineering and mechanical design, these systems are ideal for civil and mechanical engineering education courses. Materials range in complexity from single trusses to dynamic kits for design-based experimentation. This guide explains and compares all of our Structure System options and accessories.
Experiment Library
Perform the following experiments and more with the Cast Beam Spares Set.
Visit PASCO's Experiment Library to view more activities.
Bend Testing Cast Beams
In this lab, a three-point bend test is performed on Plaster of Paris cast beams and the Flexural Elastic Modulus for the material is calculated. The maximum load force at fracture is measured, and is used to calculate the Modulus...
Compression Testing Cast Beams
In this lab, Plaster of Paris cast beams are tested to destruction using compression. Quantities measured include Young's Modulus and the Compressive Strength for the material.
