2.  The strong lateral forces present at sea cause wind turbines to vibrate, or rock back and forth.  These vibrations cause the soil at the bottom of the ocean to weaken, creating a vertical angle between the pile and ocean floor.  If this angle exceeds 5 o, the wind turbine stops producing energy. Texas A&M University, Department of Civil Engineering

3.  In order to measure the strength of the soil, the research team conducted T-bar and Mini Shear Vane tests using soil mined and shipped from Florida.  Teachers were responsible for mixing powdered clay and water to a predetermined water content of 55%, and determining the soil strength by running each of the tests.  Data was collected using the T-bar, Mini Shear Vane, Basic DAQ and Smart Motor Interface computer software.  The T-bar test recorded voltages and then multiplied by the calibration factor giving force, which is an indicator of soil strength.  The Mini Shear Vane test recorded voltages and multiplied by the calibration factor giving torque.  With these different methods of collecting data, we were able to improve our understanding of the soil mechanics in the ocean.

4.  Enduring Understandings ◦ Using the Unit Circle and right triangle trigonometry, we can generate the graphs for the sinusoidal functions y = sin(x) and y = cos(x). ◦ Sinusoidal functions can be used to model real world applications – the rise and fall of tides, pendulum motion, the movement of weights supported by springs, etc. ◦ All previous transformations of functions can be applied to sinusoidal functions.

23. 7. Over the course of one day, a team of scientists has recorded the ground temperature, measured in o F, as a function of the time t, measured in hours since midnight. The scientists have agreed that this data is periodic and can be properly modeled using a sinusoidal function. Based on this model, which of the following statements is true? I. The maximum temperature in the desert occurs before 2:00 p.m. II. Between midnight and 6:00 a.m., the temperature remains below 76 o F III. The temperature in the desert is decreasing between 3:00 a.m. and 4:00 a.m. A.I only D.II and III only. B.II only E.I, II and III C.I and III only t67891215182123 oFoF7680859010410910410080
