Machine Design by Timothy H. Wentzell Chapter 2 question 3:

If we now include in problem 1 an acceleration of 16 ft/sec^2 for the first two seconds of travel for the elevator car, determine:

Force, Work, and Pore 15 ti1 FIGURE 2.4 Elevator for Problems 1 through 4. . Redoing problem 1, change the mass of the elevator car pants to 500 kg, the distance to 50 meters, and the c diameter to h meter. 3. If we now include in problem 1 an acceleration of 16 ft first two seconds of travel for the elevator car, determi a. The force in the cable during the first two seconds. b. The distance traveled during that period. c. The power d. Co ladoing problem 3, change the acceleration to 3 m/s required during the acceleration period mpare this result to the power calculated in pro hined wind r

a) The force in the cable during the first two seconds
b) the distance traveled during that period
c) the power required during the acceleration period.
d) compare this result to the power calculated in problem 1
