The manufacturer also offers the option of custom size and capacity ofthe basic design. For every model and customer option, you, as an engineer (student) in thecompany, are given the responsibility of specifying:  The material for the pins.  Dimensions of three pins A, B, and C.  The material for the structure Members 1 and 2.  The dimensions of each structural member, Member 1 and Member 2.Developing the mathematical model in symbolic form, and solving the equations with anequation solver program will create a tool for rapid and

second exam, the commonquestion involved solving for an equivalent force system for a beam subjected tovarious point loads (Figure 2). This question asked the students to replace theforce system acting on the beam by two different equivalent systems. On the thirdexam, the common question involved solving for the forces acting in a member of a2-D frame (Figure 3). In common question 3 students were given the value of Pand asked to calculate all the force acting on member A-B-D. The test questionswere graded by the same person (Vilmann), avoiding any bias that might occur dueto differences in grading schemes.For the first exam, due to a miscommunication between the two authors, thestudents in the online course had a slightly more difficult

IntroductionBeams are longitudinal members subjected to transverse loads. Students usually first learn thedesign of beams for strength. Then they learn the determination of deflections of beams under avariety of loads. Methods used in determining statically indeterminate reactions and deflectionsof elastic beams include: 2 - 1 3

Examples of this include Outcome 1-3 in Fig. 3(a) and Outcome 2-2 in Fig.3(b), which respectively are “Solve for unknown forces and moments acting on a 2-D rigidbody” and “Construct a free body diagram for a rigid body”. Both of these outcomes areintroduced early in the course and covered on the first examination, prior to the first overarchingproblem solution period.It is noteworthy that an increase in ratings is shown for all 28 learning outcomes. As expectedfor the reason described above, the most significant increases tend to occur on the learningoutcomes that have the lowest pre-survey scores.

Using the load-displacement relationship, aswell as the fact that the relative displacement between the bone and nail is 0, the followingrelationships can be developed:where F is force, L is the length, A is the cross-sectional area, % is the percent of bone loss, E isthe elastic modulus, and σ is the stress. The subscript B represents values of the bone, and thesubscript N represents values of the nail. Synthes, the producer of the nail and screws, uses atitanium alloy Ti–6Al–7Nb.[6] Therefore, the elastic modulus used for the nail was 114GPa,[7]and the elastic modulus for the bone was 18.6GPa.[8.9] Due to their complex geometries, thearea of the nail was calculated as an area formed by 2 concentric circles, while the area of
