Machine Design Innovation via MotionGen Anurag Purwar∗ , Pranav Korrapati, Q. J. Ge, Xin Ge Computational Design Kinematics Lab Mechanical Engineering, Stony Brook University, New York, USA ∗ Corresponding author (email: anurag.purwar@stonybrook.edu) AbstractThis paper presents MotionGen, an app for iOS and Android platforms, that solves the motiongeneration problem for planar four-bar mechanisms. A critical and early stage goal in the machinedesign process is generation and evaluation of mechanism design concepts that can potentiallydrive a machine. The app provides best types and dimensions of four-bar

can be further challenged by asking them to minimize heat transfer byoptimizing the height of the tank, while keeping the volume constant. The goal in this case is tominimize Q by reducing surface area, which is a function of tank height (H) and radius (r1), asshown in Eq. 4. Since tank volume is constant, Eq. 5 can be substituted into Eq. 4 for r1 to obtainAs as a function of H. The tank height that provides the minimum surface area can then be found Spring 2015 Mid-Atlantic ASEE Conference, April 10-11, 2015 Villanova Universityby taking the derivative of As(H) and setting it equal to zero. This optimum value of H can thenbe used to find the minimum insulation thickness
