Problem 14.16 A milled-teeth steel pinion and gear pair have Sut = 125 kpsi, Sy = 102 kpsi and a hardness at the involute surface of 292 Brinell. The diametral pitch is 3.5 teeth/in, the face width is 2 in, and the pinion speed is 675 rev/min. The tooth counts are 19 and 80. Use the Gerber criteria to compensate for one-way bending. For a design factor of 2.0, rate the gearset for power considering both bending and wear.

Which property of fossils allow scientists to determine the relative rock ages..

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
