1. The fundamental vibration of 1H19F is at 3961.64 cm-1. Using the harmonic oscillator model, calculate the “force constant” of the bond (in N/m) and use this value to predict the fundamental frequency of both 2H19F and 1H18F in wavenumbers. Briefly explain why the fundamental frequencies are so different. (amu masses: 1H = 1.0078, 2H = 2.0140, 18F=18.0009, 19F=18.9984) 2. What is the fundamental frequency of the vibrational mode best described by the term “symmetric stretch”?

1. Calculate an approximate value for the centripetal force acting on the Earth due to the sun. Assume the Earth travels on a circular path about the sun (in reality its slightly elliptical) and use the average Earth-Sun distance in your calculation. What familiar force is acting as the centripetal force in this situation? 2. In this experiment, what familiar force is acting on as the centripetal force on the object undergoing circular motion?

2. [24%] A M 10kg motor running at the speed of 300 rpmwas found to produce excess vibration due to rotation unbalance (see right figure). The unbalance was estimated moe 0.2 kg. m. The situation is to be rectified using vibration isolator as the excess vibration exceeds the allowable force transmission to the ground F100 N. In the analysis, the isolator is modeled using a spring (k) and damper element (e). Answer the following questions. (a) [4] Assume zero damping...
