FLUID MECHANICS - CASE STUDY

    Introduction


Canoe

 

In preparation for the upcoming Concrete Canoe Competition, the University of Oklahoma chapter of the American Society of Civil Engineers (ASCE) is currently soliciting design ideas from its student members. Two canoe design layouts (as shown in the figures) have been received so far. These designs are similar in shape but with different dimensions. Assume either canoe weighs 120 pounds and the total weight of the paddlers and gear is 630 pounds.

  Question

 

Based on a simple buoyancy analysis, determine if the designs will float or sink by calculating the submerged waterline.

   
  Approach

 
  • For a simple analysis, use a single concentrated load instead of distributed load.
  • Assume a water density of 1.94 slugs/ft3.
