The decay of a radioactive isotope can be theoretically modeled with the following equation, where C 0 is the initial amount of the element at time zero and k is the decay rate of the isotope. Create a proper plot of the decay of isotope A [ k = 1.48 hours]. Allow time to vary on the abscissa from 0 to = hours with an initial concentration of 10 grams of isotope A. C = C 0 e − t / k

Required information
An abrasive cutoff wheel has a diameter of 5 in, is 1/16 in thick, and has a 3/4-in bore. The wheel weighs 4.80 oz and
runs at 11,700 rev/min. The wheel material is isotropic, with a Poisson's ratio of 0.20, and has an ultimate strength of 12
kpsi.
