In your first assignment as Chief Dessert Engineer for the United Cookie Corporation, you design acookie whose interior is a layer of marshmallow surrounded by a ring of chocolate. The top and bottomare round graham crackers, to which the marshmallow and chocolate are attached securely.After the graham crackers are attached, and the entire cookie is in equilibrium at 10°C, there is nostress in the marshmallow or chocolate. The chocolate will separate from the graham cracker if the(vertical) tensile stress in the chocolate exceeds 1.3 × 10³ Pa. What is the maximum temperatureincrease the cookies can withstand without the chocolate separating?chocolate separatingChocolate: Y = 1.5 × 10$ Pa and a =0.0010KMarshmallow: Y = 1.0 × 10ª Pa, a = 0.0025K1%3DAssume the graham cracker does not bend and ignore effects related to expansion in the horizontdirections.15

A disk of SBR elastomer 3.0 cm in diameter 0.5 cmthick is used as a cushioning surface between two steel rods ofthe same diameter, as shown below (not to scale). a. If the rods are brought together with an axial force of 100 N such that the SBR is compressed elastically between them, what is the thickness of the SBR under load? b. Under the same conditions as part (a), what is the greatest possible diameter of the SBR under load? c. If the SBR is bonded to the rods, how far can one rod be rotated with respect to the other before the SBR/rod interface fractures? Assume that the rods are essentially rigid and the distance between them remains constant. Please answer in degrees of rotation.
A spherical gas-storage tank with an inside diameter of 26 ft is being constructed to store gas under an internal pressure of 187 psi.
