31. In the case where velocity is parallel to acceleration ( for example, linear motion ), the formula simplifies to 32. In engineering, the term may also refer to a variety of transducer devices that convert energy into linear motion . 33. The Ragonnet power reverse mechanism was a general purpose air or steam-powered servo amplifier for linear motion patented in 1909. 34. The shape of the nozzle also modestly affects how efficiently the expansion of the exhaust gases is converted into linear motion . 35. Combined with this predominantly modular organization of material is a powerful sense of linear motion frequently provided by the band's lyrics. 36. The rod is then connected to a valve stem which allows the valve to experience the linear motion thereby opening or closing. 37. During battle sequences, the game uses the " Cross Dual Raid Linear Motion Battle System ", a similar system to the prequel. 38. These three acquisitions have made Schaeffler Group AG one of the largest producers of rolling bearings and linear motion products in the World. 39. Each form has an overall guiding significance, which may range from balance and linear motion to preparation and practice for a knife form. 40. The linear motion should be the same regardless of where on the object it's applied, so there does appear to be a paradox.
