Mechanical 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.

Drive Wheel Motor Torque Calculations

mae.ufl.edu

Drive 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.)
