Abstract

Development of Low-Cost, Hands-On Lab Experiments for an Online Mechanics of Materials CourseOnline education has expanded quickly in recent years and offering an engineering curriculumonline has been limited by the ability to replicate lab experiments that are integral to somecourses. Some approaches to lab experiments in distance education or online courses have beenattempted including recording video of lab experiments or creating simulations of laboratoryexperiments that run virtually via the internet. This paper outlines the development of a set ofinexpensive, transportable lab experiments for students in a mechanics of materials courseoffered via distance education. The set of labs were developed to allow for hands-on learningwith a kit of supplies and a list of experiments that students could perform at home using readilyavailable materials. The labs were developed using materials that had properties whichmimicked the behavior of traditional materials like steel or aluminum, but exhibited thosebehaviors at much lower applied loads and stresses. Most labs allowed for actual data to betaken and analyzed while a few labs demonstrated the concept qualitatively. These labs wereinitially integrated into an existing Mechanics of Materials course offered via audiographics andwill be offered in conjunction with an online course in a coming semester. A pretest and posttestwere given to determine how comfortable students were with laboratory concepts before andafter the course. In addition, and a short questionnaire was administered after each lab to getfeedback from students about the implementation of the lab and its helpfulness in understandingmechanics of materials topics.
