Paul Petricca draws on his experience as a coach, player, blogger, and student of baseball and softball to share what hes learned about hitting in this essential guide for players seeking dramatic results at the plate. The author presents easy to understand hitting mechanics highlighting how the engineering concept of torque can be applied to hitting and is often the difference between a weak groundball or a long home run. Topics covered include understanding where hitting power really comes from and the importance of increasing bat speed through the fundamentals of a repeatable and powerful rotational swing. Hitters of all ages who adopt his eight hitting keys will enjoy a dramatic increase in bat speed and power almost immediately. Hitting with Torque is more than a set of hitting mechanics---its a mindset. Readers will be challenged to look past the worn-out hitting theories and myths that have been holding back hitters from reaching their full potential. With an open mind and practice, all hitters can unlock the power and consistency that is Hitting with Torque.

Many people modify their Harley-Davidson engines--and find the results disappointing. What they might not know--and what this book teaches--is that emphasizing horsepower over torque, the usual approach, makes for a difficult ride. Author Bill Rook has spent decades perfecting the art of building torque-monster V-twin Harley engines. Here he brings that experience to bear, guiding motorcycle enthusiasts through the modifications that make a bike not just fast but comfortable to ride. With clear, step-by-step instructions, his book shows readers how to get high performance out of their Harleys--and enjoy them, too.

The maximum torque a seated operator can apply in turning a knob with the bare thumb and fingertips of his right hand was determined. Effort was made to develop a procedure by which a given knob or set of knobs may be evaluated with respect to maximum torque exertable. A set of 60 knobs, each 1/2 inch thick, was used. The knobs had 20 diameters from 1/8 to 5 inches. For each diameter there were three different rim surfaces: mooth, rectangular-knurl, and diamond-knurl. Each of 45 subjects was tested with every diameter-surface combination. In addition, 15 of the subjects repeated the experiment. The maximum torque exertable increased with knob diameter. For all knob sizes, rectangular- and diamond-knurled knobs permitted greater torques than did smooth kno s. Very little difference in maximum torque exertable was observed between the rectangular and diamond-knurled surfaces.
