Data for Problems 1 through 3

Tape Weight: 2.0 lbs.
Standardized Length: 100.02' @ 68o F
Cross Sectional Area: .0065 square inches
Modulus of Elasticity: 29,000,000 psi
Tension @ Standardization: 20 lbs.

1.Your crew measured a distance of 450.00 feet between two existing points fully supported on a 68o F day using a tension of 20 lbs. What is the most probable distance (16 Points)?

2.Your crew measured a distance of 550.32' between two existing points fully supported on a 51o F day using a tension of 20 lbs. What is the most probable distance (17 Points)?

3.Your crew measured a distance of 800.00' between two existing points on a 68o F day having only the ends of the chain supported using a tension of 20 lbs. What is the most probable distance (17 Points)?
