Introduction to the Design Process - University of Florida
eving the score of 10 (out of 10), and the score for the welded plate design was computed as $2200 / $2500 * 10.0 = 8.8. Magnitude is the assigned value of each objective, whether quantitative or qualitative. Score is the relative comparison of the different magnitudes.

Fundamental Principles of Mechanical Design
mae.ufl.eduMechanical Design Fundamentals K. Craig 20 Laws of Nature • To develop a physical model of an existing system or of a system concept, we use engineering judgment and make simplifying assumptions. • To develop a mathematical model, a model that can predict system dynamic behavior, we apply the Laws of Nature to the physical model.
Useful Motor/Torque Equations for EML2322L
mae.ufl.eduCalculate the Torque required to lift the Force with the lever arm . T = F x d = 49.05 N x 0.5 m = 24.525 N-m . We cannot perform the lift with this set-up, because the stall torque is smaller than . the torque required for the lift. We must either shorten the length of the lever arm,

[Figure 2-5] The most popular types of fuselage structures used in today’s aircraft are the monocoque (French for “single shell”) and semimonocoque. These structure types are discussed in more detail under aircraft construction later in the chapter. Wings
Drive Wheel Motor Torque Calculations
mae.ufl.eduDrive Wheel Motor Torque Calculations . Step Four: Determine Total Tractive Effort . The Total Tractive Effort (TTE) is the sum of the forces calculated in steps 1, 2, and 3. (On higher speed vehicles friction in drive components may warrant the addition of 10%-15% to the total tractive effort to ensure acceptable vehicle performance.)
Drilling Speeds and Feeds - University of Florida
mae.ufl.eduEquation 2 will provide a guideline as to the maximum speed when drilling standard materials. The optimum speed for a particular setup is affected by many factors, including the following: 1. composition, hardness, and thermal conductivity (k) of material 2. depth of hole 3. efficiency of cutting fluid 4. stiffness and condition of drilling ...
