Pressure | Forces | Physics A. Strip and Wire Testing Clamps
Strip and wire testing clamps provide a simple and effective clamping system for wires, threads and strip materials to be investigated for breaking strain, stretch etc. Follow the instructions provided to clamp the material in place and apply loads. Investigations would include strength and stretch comparisons of sewing threads, fishing line, ductile wires such as copper, human hairs etc. Strips of plastic, paper and fabrics can also be investigated.
Full instructions included. Max load 10kg. E8R07375
