9 Given: A mechanical system is shown on the right. You may neglect the masses of the pulleys and cords, and you may assume that the block is initially at rest. Find: a) The kinematic (i.e., dependent motion) equations for the motor-pulley system. This includes the equations for B position, velocity, acceleration, and displacement b) The displacement of block A if the motor pulls down the D cord, which connects motor M and pulley...

The vocal cords, two lipshaped memrane folds in the upper
trachea as indicated in the figure, are responsible for vocal sound
production. The voices of males and females often have different
sonic characteristics: Male vocals have an average fundamental
frequency of about 140 Hz, while female vocals have an average of
about 230 Hz.
