The lively and fascinating story of baseball’s 150-year hunt for the perfect pitch In August 2012, Felix Hernandez of the Seattle Mariners pitched a perfect game against the Tampa Bay Rays in what Terry McDermott calls “one of the greatest exhibitions of off-speed pitches ever put on.” For McDermott, a lifelong fan and student of baseball, the extraordinary events of that afternoon inspired this incisive meditation on the art of pitching. Within the framework of Hernandez’s historic achievement, Off Speed provides a vibrant narrative of the history and evolution of pitching, combining baseball's rich tradition of folklore with the wealth of new metrics from a growing legion of statisticians who are transforming the way we think about the game. Off Speed is also the personal story of a fan’s steadfast devotion, first kindled in McDermott by his father at the local diamond in small-town Iowa and now carried forward with the same passion by his own daughters. Approaching his subject with the love every fan brings to the park and the expertise of a probing journalist, McDermott explores with irrepressible curiosity the science and the romance of baseball.

A wonderfully informative, exuberant, and entertaining book that explores the evolution and history of baseball pitching through the story of one “perfect” game. Tracing the evolution of pitching and the pitcher's art of deception, Terry McDermott tells the fascinating story of baseball's 150-year hunt for the perfect pitch. Using the framework of a single game (nine chapters, nine innings, nine pitches), he explores the history of every type of pitch, combining the folk wisdom of the players with the enormous wealth of new data brought to the sport by the growing legion of statisticians who are transforming many of the sport's once sacred beliefs. As a lifelong baseball fan, McDermott approaches his subject with the love every fan brings to the park plus the expertise of a probing journalist, exploring with irrepressible enthusiasm and curiosity both the science and the romance of the game.

Metal mesh foil bearings (MMFBs) are a promising low cost gas bearing technology for support of high speed oil-free microturbomachinery. Elimination of complex oil lubrication and sealing system by installing MMFBs in oil free rotating machinery offer distinctive advantages such as reduced system overall weight, enhanced reliability at high rotational speeds and extreme temperatures, and extended maintenance intervals compared to conventional turbo machines. MMFBs for oil-free turbomachinery must demonstrate adequate load capacity, reliable rotordynamic performance, and low frictional losses in a high temperature environment. The thesis presents the measurements of MMFB break-away torque, rotor lift off and touchdown speeds, temperature at increasing static load conditions, and identified stiffness and equivalent viscous damping coefficients. The experiments, conducted in a test rig driven by an automotive turbocharger turbine, demonstrate the airborne operation (hydrodynamic gas film) of the floating test MMFB with little frictional loses at increasing loads. The measured drag torque peaks when the rotor starts and stops, and drops significantly once the bearing is airborne. The estimated rotor speed for lift-off increases linearly with increasing applied loads. During continuous operation, the MMFB temperature measured at one end of the back surface of the top foil increases both with rotor speed and static load. Nonetheless, the temperature rise is only nominal ensuring reliable bearing performance. Application of a sacrificial layer of solid lubricant on the top foil surface aids to reduce the rotor break-away torque. The measurements give confidence on this simple bearing technology for ready application into oil-free turbomachinery. Impact loads delivered (with a soft tip) to the test bearing, while resting on the (stationary) drive shaft, evidence a system with large damping and a structural stiffness that increases with frequency (max. 200 Hz). The system equivalent viscous damping ratio decreases from ~ 0.7 to 0.2 as the frequency increases. In general, the viscous damping in a metal mesh structure is of structural type and inversely proportional to the frequency and amplitude of bearing motion relative to the shaft. Impact load tests, conducted while the shaft rotates at 50 krpm, show that the bearing direct stiffness is lower (~25% at 200 Hz) than the bearing structural stiffness identified from impact load tests without shaft rotation. However, the identified equivalent viscous damping coefficients from tests with and without shaft rotation are nearly identical. The orbits of bearing motion relative to the rotating shaft show subsynchronous motion amplitudes and also backward synchronous whirl. The subsynchronous vibration amplitudes are locked at a frequency, nearly identical to a rotor natural frequency. A backward synchronous whirl occurs while the rotor speed is between any two natural frequencies, arising due to bearing stiffness asymmetry.
