\"IMG_2232\"<\/a>By chucking jack-o-lanterns across the West Lawn Nov. 1, two UCCS faculty members hope to demonstrate the value of interdisciplinary cooperation and hands-on learning.<\/p>\n

For the second year, Roger Martinez, assistant professor, Department of History, and Michael Calvisi, assistant professor, College of Engineering and Applied Sciences, will bring history to life by recreating an medieval weapon. From 11 a.m. to\u00a0 1 p.m. on Nov. 1 on the West Lawn, engineering and history students will deploy a handmade one-fifth scale 13th<\/sup> century Cantigas de Santa Maria Trebuchet, chucking pumpkins to demonstrate engineering and historical principles.<\/p>\n

Those who bring projectiles will be entered into a raffle for prizes including a pumpkin spice latte.<\/p>\n

Faculty, staff and students are asked to bring Halloween remnants to the event and to participate in the demonstration of a weapon popular in the era before gunpowder. In its heyday, trebuchets were used to hurl projectiles \u2013 mostly rocks — at enemies.<\/p>\n

\u201cWe\u2019re making some enhancements from last year\u2019s model,\u201d Martinez said recently. \u201cEven though it\u2019s old technology, it\u2019s still evolving.\u201d<\/p>\n

Martinez uses the trebuchet as part of his History 1020 Medieval World class and in support of a curriculum called Reacting to the Past. For the past month, the oak-hewn trebuchet has been displayed in the atrium of El Pomar Center, complete with its own oversize campus parking pass.<\/p>\n

\u201cDean Switzer was gracious and allowed us to park the trebuchet outside of the library,\u201d Martinez said. \u201cBut we all know everything at UCCS needs a parking permit.\u201d<\/p>\n

As part of the curriculum, students experience history by re-enacting it. Students in Martinez’s course are studying the Crusades and debating Christian and Islamic perspectives of “Just War.” By building\u00a0a machine of war and putting it into action, Martinez believes students are experiencing history in a unique, hands-on way that makes an indelible impression.<\/p>\n

\"IMG_2219\"<\/a>Building on the efforts of students last year, this year\u2019s students are in the process of constructing a new counterweight box to\u00a0hurl the\u00a0 light-but-large pumpkin projectiles. The larger box will allow more counterweight and increase the distance a five-pound pumpkin will fly.<\/p>\n

That\u2019s where Calvisi and the members of the Historical Engineering Society come in.<\/p>\n

Calvisi will lead student engineers in analyzing the trajectory of the projectile and overseeing the production of the new counterweight box. Last year, engineering students conducted a stress analysis of the trebuchet designs to evaluate how oak frames handle the imposed loads. The\u00a0students learned skills that could be applied to the workforce.<\/p>\n

\u201cThe engineering process is the same,\u201d Calvisi said. \u201cIt doesn\u2019t matter if you\u2019re\u00a0designing a trebuchet or an airplane. The students were able to apply what they learned in a classroom to an actual engineering device and then related this in a job interview.”<\/p>\n

The engineers will also work through safety protocols in conjunction with the history students, again combining skills toward a common goal.<\/p>\n

\u201cI\u2019m sure there were plenty of accidents using these weapons. Commoners lives held little value during the Middle Ages,\u201d Martinez said. \u201cThat\u2019s one part of history we\u2019re not interested in. We are fortunate beneficiaries of the European Enlightenment and the value of everyone.\u201d<\/p>\n
