Question

The structural engineering design section within the engineering department of a regional electrical utility corporation has developed several 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 46 towers has been approved. The estimated number of engineering hours needed to accomplish the first detailed tower design is 124. Assuming a 94​% learning​ curve, what is your estimate of the number of engineering hours needed to design the eighth tower?

Answer 1

102.99 hours needed

Step-by-step explanation:

Zu = K (U^n)

Zu= estimation of tower which is for 8

U= number of tower which is 8

n= log0.94/log2

`Zu= 124(8^(log0.94/log2) )= 102.99hours`
