Pumpkin, squash and sunflower seed kernels are all rich in both zinc and copper. Roasted pumpkin and squash seeds contain 9 milligrams of zinc per cup, while toasted sunflower seeds contain 7 milligrams in every cup.
Mechanical designers create designs for machines and mechanical devices. They combine drafting skills with mechanical engineering knowledge to assist product development engineers in the manufacture of new mechanical devices.echanical designers must have expert knowledge of mechanical and electrical engineering, computer drafting programs, and physical construction techniques. A career as a mechanical designer requires an aptitude for drawing.
Mechanical engineers design a wide range of products, such as toys, turbines, and spacecraft. As a mechanical engineer, you'll apply concepts of energy transfer, conversion, and manufacturing to create functional designs. This may entail exhaustive research combined with an extensive knowledge of materials and mechanics.
