20-Peg Wall-Mounted Plastic Draining Rack with Collection Tray Physics_Electricity & Magnetism applying tension to material strips

applying tension to material strips until failure for breaking-strain and tensile-strength measurement in materials-science work

sized as a load that visibly spins when current flows in the circuit

the optical-grade crown body producing low-dispersion baseline measurements in refraction comparison studies

producing more sinusoidal oscillation than a standard helical spring for SHM studies

and washable
