Computer-based learning aids for constructing shear force and bending moment (V/M) diagramsare especially appealing to engineering mechanics instructors for the following reasons:• Many statics students fail to master this topic, which is essential for successful designof beams and shafts in courses such as Mechanics of Materials, Machine Design,Structural Analysis, and Structural Design.• The construction of V/M diagrams tends to be a time-consuming process, especiallywhen presented in traditional lecture format.The format of computer-based modules for construction of V/M diagrams varies widelydepending on the solution method and intended use. Basic calculation packages allow thestudent or instructor to define loads on a beam and produce the resulting V/M diagrams [1-2].They also serve as a resource for students to check assigned problems or for instructors toconstruct new problems. Modules intended for use as student problems (assigned or practiceproblems) usually require the student to construct some portion of the diagram or make decisionsabout the solution method [3-4]. More recent interactive modules provide questions andfeedback intended to mimic thought processes for successful construction of V/M diagrams. Forexample, a computer-based module can be used to provide a series of questions that guide the
