A 200-metric ton, rectangular barge is 14 m long, 8 m wide and 4.5 m deep. The barge will transport 20- mm diameter steel bars that are 6 meters long and weighs 7850 kg/m³. (HINT: 1 metric ton = 1000 kg) If the draft of the barge is maintained at 3 m in salt water (p = 1026 kg/m³), how many steel bars can it carry? Round up your answer to next whole number. b. What is the draft of the barge if one half of the cargo is unloaded in fresh water (p = 1000 kg/m³)? If the draft of the barge in fresh water is maintained at 2 m, how many steel bars can it carry? Round a. %3D с. up your answer to next whole number.
