3. The circle near the south-west corner of OSU-Cascades Campus has a radius of about 25.0 meters. Suppose a cyclist is traveling around the circle at the maximum speed possible and is leaning at a constant 10.4 degrees relative to the vertical as shown in the image below. Use a torque analysis, with a reference axis at the center of mass, to determine the coefficient of static friction between the tires and the road. (Hint: The cyclist has no angular acceleration about the center of mass.)
