Limit fit & Tolerance

Limit fit & Tolerance : Unilateral tolerance :variation is only one direction Bilateral tolerance : variation on both side Fundamental deviation: basic size Tolerance = upper limit - lower limit :Permissible limit of variation for manufacturing is assigned to parts for manufacturing purpose as boundary of acceptable build. Basic size : Nominal diameter of shaft or hole it is same for both Fit : it is clearance between two mating parts, it can be determined by whether the parts move, temporary joint ,permanent joint. Clearance fit : Hole is larger than shaft. Transition fit : Hole is fractionally smaller than shaft. Interference fit : Hole is smaller than shaft. Functional dimension : have to be machined and fit with other mating parts. Drilling : unilateral Dimension BIS (Bureau of International Standard) Grade of Tolerance :18 Fundamental tolerance : 25 BSI (British standard System) ...

Hydraulic & Fluid Mechanics

Hydraulic & Fluid Mechanics Density/Mass density : mass/unit volume at standard temp and pressure. rho =M/V unit: kg /me Weight density/specific weight : weight /unit volume at standard temperature and pressure. w=rho x g unit : N/me Specific volume : volume/unit mass of liquid v=V/m unit : m3/ kg Specific gravity : it is defined as specific weight of liquid to specific weight of pure water at 4 degree C it has no unit Viscosity : it offers resistance to movement of one layer of liquid to another layer Compressibility : properly change in volume to change in pressure. it is reciprocal of bulk modulus of elasticity. Surface tension : property of liquid which enables to resist tensile stress denoted by sigmaunit : N/m Capalary : phenomena of rise /fall of surface in small tube held in liquid relatives. Pressure of liquid : When liquid contained in vessel it exerts at all points on side & bottom of vessel force per uni...

Engineering Mechanics

Engineering Mechanics Branch of engineering science which deals with principle of mechanics and application of engineering problems There 2 types of Mechanics 1. Static mechanics : it Deals with force and there effect which deals at rest. 2. Dynamic mechanics : it Deals with force and there effect which deals at motion. in dynamic there are 2 types Kinetics : it Deals with force and there effect which deals at motion due to application of force Kinematics : it Deals with force and there effect which deals at motion without taking in account force which responsible for motion. Force : it produce or tends to produce , destroy of tends to destroy the motion of body, which acting on bod...
