The Mechanicals

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 ...

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...
