From an ecological perspective, seal dust plays a crucial role in nutrient cycling within marine environments. The organic matter released into the ecosystem can serve as a food source for various microorganisms, subsequently supporting the entire food web. Phytoplankton, the primary producers of marine environments, benefit from the nutrients in seal dust, which can enhance their growth and, in turn, bolster the populations of herbivorous marine organisms.
The expansion of the brake shoes is facilitated by a cam mechanism, which converts the linear motion of the brake pedal into the radial movement of the shoes. The cam rotates and pushes the shoes outward, increasing contact with the drum surface. Friction between the shoes and the drum generates the necessary braking force to slow down or stop the vehicle.
