Diy Sink Stopper !!top!! Here

Let (F_thumb) = 10 N (typical thumb force). The weight (W) = 2.5 N. Total axial force (F_axial) = 12.5 N. Axial stress on silicone: (\sigma_a = F_axial / A_cross). Due to Poisson’s ratio, radial seal force (F_radial = \mu \sigma_a) where (\mu) is coefficient of friction between silicone and stainless drain ((\mu \approx 0.8) dry, 0.6 wet). Thus (F_radial \approx 7.5) N – sufficient to seal against 0.3 m water head (which requires only ~1 N of radial force).

The DIY sink stopper design consists of a plastic bottle, a metal wire, and a few simple tools. The plastic bottle is cut to create a cylindrical shape, which serves as the main body of the stopper. The metal wire is shaped to create a spring-like mechanism that connects the plastic bottle to the sink drain. The DIY sink stopper is easy to assemble and disassemble, making it simple to clean and maintain. diy sink stopper
