The roof truss system is a crucial part in the home construction process with the truss type used largely affected by the roof span, calculated weight load {taking into consideration both the weight of the materials used and the projected snow drifting}, and wind load or the pressure a roof must endure when the wind is blowing against it. After researching roof structure, Scotty was interested in finding out, all else being equal, which type of truss - the Graf-post, King-post, and Queen-post trusses - would hold the most mass before breaking under the pressure.\u003c\/p\u003e\n\u003cp\u003eMaking models of all three truss types from thin balsa wood, Scotty used a Vernier force plate to measure the Newtons of force sustained by each model before they failed. [NOTE: We weren't familiar with the technology and upon further investigation, noticed that it can be quite pricey. \u003ca href=\"http:\/\/www.selah.k12.wa.us\/SOAR\/SciProj2004\/CamdonA.html\" target=\"_blank\" data-ad-id=\"post-content-link\"\u003eSelah School District\u003c\/a\u003e sixth grader, Camdon A., did a similar project, but used another method to measure the force sustained.
