6. Two 8 x 4 x 1 inch blocks of foam are glued together (one block on top of the other) and used to support the bottom face of a product. The product weights 15 pounds. The stiffness of each of the blocks respectively is 50 lb/in and 25 lb/in. When the product is placed on the blocks of foam ... a) What is the total foam deflection? b) What is the static load on the foam block? c) What is the natural frequency of the total system?
