1.General price inflation is estimated to be 3% for the next 5 years, 5% the 5 years after that, and 8% the following five years. If you invest $10,000 at the market rate of 10% for those 15 years, what is the future worth at 15 years of your investment in then-current dollars and in year-0 dollars?
2.A structural element subjected to cyclic loading is made of fc’ = 3000 psi concrete. Compressive stresses are changing between 2200 psi and 1600 psi. The frequency of loading is 8 Hz. After 10 years of uninterrupted loading, evaluate damage of material, compressive strength and modulus of elasticity.
