Determine the horizontal length of CD that must be laid out to achieve the required true horizontal distance CD. Assume a 100-ft steel tape will be used, with a cross-sectional area of 0.0060 in^2, weight 2.0 lb, and standardized at 68°F to be 100.014 ft between end marks when supported throughout with a 12-lb pull.

a. 123 ft
b. 169 ft
c. 200 ft
d. 378.68 ft

Final answer:

It is not possible to determine the horizontal length of CD without knowing the diameter of the tape.

Step-by-step explanation:

To determine the horizontal length of CD, we need to use the formula: L = (D^2 - d^2) / (2d), where L is the length of CD, D is the distance between the end marks on the tape, and d is the cross-sectional diameter of the tape. The given information states that the tape has a cross-sectional area of 0.0060 in^2 and a weight of 2.0 lb. However, we also need to know the diameter of the tape in order to calculate the length of CD. This information is not provided in the question, so it is not possible to determine the correct answer.
