A major part of the torque is due to friction, so the differences in friction can cause large variations of the preload with the same torque setting; [3] angle-controlled tightening (also known as turn-of-the-nut method) is a technique where the bolt joint is rotated to some angle that ensures the stress beyond the yield limit of the parts ...
The VK56VD is a 5,552 cc (5.6 L; 338.8 cu in) 32-valve, DOHC, Direct Injection Gasoline aluminum-alloy V8 and features Nissan's latest VVEL (Variable Valve Event & Lift System). The direct injection system provides better wide-open throttle performance and improved fuel economy and emissions performance by reducing engine knock, improving ...
The side of the threaded fastening having the least friction should receive torque while the other side is counter-held or otherwise prevented from turning. A common relationship used to calculate the torque for a desired preload takes into account the thread geometry and friction in the threads and under the bolt head or nut.
Most commonly, these have taken the form of multiple turbines and stators, each set being designed to produce differing amounts of torque multiplication. For example, the Buick Dynaflow automatic transmission was a non-shifting design and, under normal conditions, relied solely upon the converter to multiply torque.
All M112 engines have silicon/aluminum (Alusil) engine blocks with a 90° vee angle. The aluminum SOHC cylinder heads have 3 valves per cylinder. All use sequential fuel injection with two spark plugs per cylinder. All have forged steel connecting rods, a one-piece cast camshaft, iron-coated aluminum pistons and a magnesium intake manifold.
The torque applied to the fastener must be determined such that it does not contribute to a service condition where the fastener enters a low-cycle fatigue regime. In general, the use of torque-to-yield fasteners is deprecated except in cases where the materials and structures comprising the entire assembly are certified to be within tolerances ...

Torque density is a measure of the torque-carrying capability of a mechanical component. It is the ratio of torque capability to volume and is expressed in units of torque per volume . Torque density is a system property since it depends on the design of each element of the component being examined and their interconnection.
