Chapter 1, Problem 2RT

You have started a patient on a new drug. Each dose introduces 40 pg/mL of drug after redistribution and prior to elimination. This drug is administered at 24 h intervals and has a half life of 24 h. What will the concentration of drug be after each of the first six doses? Show your work a. What is the concentration after the first dose?  in pg/mL b. What is the concentration after the second dose?  in pg/mL c. What is the concentration after the third dose?  in pg/mL

A complete tensile test was performed on a magnesium specimen of 12 mm diameter and 30 mm length, until breaking. The specimen is assumed to maintain a constant volume. Calculate the approximate value of the actual stress at breaking. TABLE. The tensile force F and the length of the specimen are represented for each L until breaking.
