Q. The structural engineering design section within the engineering department of a regional electrical utility corporation has developed numerous standard designs for a group of similar transmission line towers. The detailed design for each tower is based on one of the standard designs. A transmission line project involving 50 towers has been approved. The estimated number of engineering hours required to accomplish the first detailed tower design is 126. Assuming a 95% learning curve, (a) Illustrate what is your estimate of the number of engineering hours required to design the eighth tower also the design the last tower (the fiftieth tower) in the project
