Strength of Material

Strength of Material Mechanical Properties Hardness ;Resist the penetration (impact  load) Strength : Ability of material withstand of material without failure. Elasticity : It regain the original shape after removing load Plasticity : Permanent deformation after removing load. Mali ability : Converts to thin sheet without rupture Ductility : Draw in to thin wire. Brittleness : No deformation takes place & rupture (lake of ductility ) (cast iron) Toughness : absorb energy & plastic deformation without rupture. Fatigue: by repeatedly applied load program me and localized structure damage that occur. Creep : tendency of solid material to move slowly deform permanently under mechanical stress. Stress : Load applied on particular area.  it is tensor quantity  unit : N/mm2 Strain : Change in length to original length when force applied on body. it has no unit. Strength of Material Tensile : when body is subjected to equal and opposite ...

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...
