Set of two crossed polarizing sheets which display stress lines as beams as submit to three-point bending tests.
See stress lines by bending a clear, colorless photoelastic I-beam between two polarizing sheets. As the beam is bent, areas of greater stress show up as patterns of colored lines.

Combines features that significantly improve the ease of setup, the durability of the Torsion Band and the quality of results. In the newer models the spheres are tungsten rather than lead.
Designed for experiments involving low light level conditions. ScienceWorkshop version.
Allows students to conduct experiments to measure the speed of light. Reflect a laser off a movable mirror into a light receiver to measure phase differences.
LED Light Source with adjustable brightness control, for use with Millikan Oil Drop Apparatus.
Allows a rotary motion sensor to mount on a Dynamics Track and act as a high resolution bi-directional Smart Pulley.
The Stress Strain Apparatus lets students observe stress and strain as they stretch a material to the point of fracture.
Replacement test coupons for the Stress/Strain Apparatus.
Slides through a special slot in the Rotary Motion Sensor and allows you to measure short linear distances.
A 2000 turn wire coil on one end of a wand that has two terminals at the other end to accommodate banana plug contacts, permitting easy connection of an electric circuit.
Allows students to measure angular velocity, acceleration, centripetal forces, and other full range of motion experiments.
