2. Trellises Ideal for climbing plants such as peas and beans, trellises provide a broader support structure. Made from lattice, wire, or even natural materials like bamboo, trellises allow plants to climb vertically, saving space and promoting healthy air circulation.

When helical springs are compressed and extended, end-to-end twisting occurs. Three remedies exist with machined springs to eliminate the torsional deformation. Fix the end of the spring using any of the attachment techniques available. Or, constrain the spring end to increase the elastic rate. Or, use two concentric springs one with a right hand flexure and the other a left hand. When properly designed, the twisting of the inner spring counteracts that of the outer one. An option is to place two flexures on a single spring blank, one right hand and the other left hand. This configuration allows the interface between the two flexures to twist, but the ends do not.
