1.Statistics indicate that the world population since World War II has been growing at the rate of 1.9% per year. Further, United Nations records indicate that the world population in 1975 was (approximately) 4 billion. Assuming an exponential growth model, (a) what will the population of the world be in the year 2050? (b) When (what year) will the world population be 20 billion?

2.Draw the influence line for the tension in the cable as a point load travels across the beam. Find the maximum tension in the cable due to a live point load of 6 k on the beam.

3.The difference in elevation between two benchmarks was measured by each of three field parties using different kinds of leveling instruments. The results are Party 1, DE= 12.46 +/- 0.04ft, Party 2, DE= 12.43 +/- 0.03 ft, Party 3, DE= 12.50+/-0.06 ft. What is the weighted differance in elevation between the two benchmarks ( nearest 0.001 ft) ?
