1.Determine the required mass of block A so that when it is released from rest it moves the 5-kg block B a distance of .75m up along the smooth inclined plane in t=2s. Neglect the mass of the pulleys and cords.
2.For a 60 year record of precipitation intensities and durations, a 30 minute intensity of 2.50 inches/hour was equaled or exceeded a total of 85 times. All but 5 of the 60 years experienced one or more 30 minute intensities equaling or exceeding the 2.50 inches/hour value. Use the Weibull formula to determine the return period of this intensity using:
a) A partial series?
b) An annual series?
