1. Describe 3 different cases having corrosion by determiningthe material (the alloys with the codes and composition),describing the component having corrosion, the environment makingcorrosion to the component. You will give suggestions to the userthat will solve the corrosion problem. However, there are someconstraints that you need to check. - The reasons for the corrosionshould be different for all cases. - The environment, the material,the component should be different for all situations. - Thesuggestions that solve the corrosion problem should be differentfor all situations. - There is no option for changing thematerial.

2. Write a question about composite materials and then solve thequestion. To do that follow the steps described below. - State thehost material and fiber type. - State the composition of thecomposite material. - State type of fiber arrangement. - Give areasonable modulus of elasticity for both of the materials. - Statethe cross-sectional area of the composite material. - State thedirection of the fiber. - State the applied stress. After givingall these properties. -Compute the modulus of elasticity of thecomposite material. -Compute the loading carried by the fiber andthe host material. -Compute the strain sustained by the fiber andthe host material.
