"The condition of a part free of applied forces" Applies only when part is otherwise restrained Ⓛ U+24C1: Least material condition (LMC) "The condition in which a feature of size contains the least amount of material within the stated limits of size" Useful to maintain minimum wall thickness Ⓜ U+24C2: Maximum material condition (MMC)
This would provide a clearance fit of somewhere between 0.04 mm (largest shaft paired with the smallest hole, called the Maximum Material Condition - MMC) and 0.112 mm (smallest shaft paired with the largest hole, Least Material Condition - LMC). In this case the size of the tolerance range for both the shaft and hole is chosen to be the same ...
maximum material condition A material condition in GD&T . Means that a feature of size ( FoS ) is at the limit of its size tolerance in the direction that leaves the most material on the part.
This means that the smallest acceptable hole diameter will be 10.02 mm while the largest acceptable shaft diameter will be 10.01 mm, leaving an "allowance" of 0.01 mm. The minimum clearance between the hole and the shaft will then be 0.01 mm. This will occur when both the shaft and the hole are at maximum material condition.
The maximum stress criterion assumes that a material fails when the maximum principal stress in a material element exceeds the uniaxial tensile strength of the material. Alternatively, the material will fail if the minimum principal stress σ 3 {\displaystyle \sigma _{3}} is less than the uniaxial compressive strength of the material.
Thus in a totally ordered set, we can simply use the terms minimum and maximum. If a chain is finite, then it will always have a maximum and a minimum. If a chain is infinite, then it need not have a maximum or a minimum. For example, the set of natural numbers has no maximum, though it has a minimum.
Geometrical Product Specification and Verification (GPS&V) [1] is a set of ISO standards developed by ISO Technical Committee 213. [2] The aim of those standards is to develop a common language to specify macro geometry (size, form, orientation, location) and micro-geometry (surface texture) of products or parts of products so that the language can be used consistently worldwide.
The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
