During the Fall 2012 and Spring 2013 semesters, Dr. Palm's engineering course worked with Community Partner Arthur Lee from the Herreshoff Marine Museum to assist in the building of a 1/6th scale replica of the Reliance yacht. Students performed a structural analysis of the critical components on the 33 foot model, as well as designed a cradle that will hold it at an 150 degree angle.

Abstract

The Roger Williams University Reliance team is working in cooperation with the Herreshoff Marine Museum in Bristol, RI to create a 1/6th scale model of the 1901 Americas Cup defender, the Reliance. The project can be broken up into two sub-projects. The first, to design a museum-quality cradle to hold the 24ft fully rigged model at a 15O angle. The second sub-project is to perform full strength/structural analysis of all the critical components on the model to ensure that their strength is great enough to withstand the applied forces. This second sub-project is going to be the focus of the spring 2013 semester while the Fall 2012 semester focused on the cradle design.

After determining our final cradle design, structural analysis validated the use of two square channel 4”x4”x0.5” steel columns for the ‘legs’ of the cradle, while 3/8” bolts secured C 3x3.5 A36 steel outrigger beams to the center beam constructed of American Standard S 3x5.7 A36 steel.
