1-Our balance is maintained, at least in part, by the endolymph fluid in the inner ear. Spinning displaces this fluid, causing dizziness. Suppose a dancer (or skater) is spinning at a very fast 2.6 revolutions per second about a vertical axis through the center of his head. Although the distance varies from person to person, the inner ear is approximately 7.0 cm from the axis of spin.
Part A What is the radial acceleration (in m/s2 ) of the endolymph fluid?
Part B.What is the radial acceleration (in g's) of the endolymph fluid?
2-A model of a helicopter rotor has four blades, each of length 4.00m from the central shaft to the blade tip. The model is rotated in a wind tunnel at a rotational speed of 540rev/min.
A-What is the linear speed of the blade tip?
B-What is the radial acceleration of the blade tip expressed as a multiple of the acceleration of gravity, g?
