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 
  1. Kinetics:  it Deals with force and there effect which deals at motion due to application of force
  2. 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 body.


Resultant force: it can be define by 3 system
  1. Parallelogram law of force 
  2. Triangle law of force
  3. Polygon law of force
Co planer force: W hoes line of action lies on the same plane.
Concurrent force: The force which meets at one point.
Non-Co planer force: W hoes line of action not lies on the same plane.
Non-Concurrent force: The force which do not meets at one point.


Engineering Mechanics

Lami s theorem: 

3 co planer force acting at a point be in equilibrium each force is praposnal to sine of angle between two force

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 ...

Important point of Strength of material

Important point of Strength of material Stress : P/A =N/mm2 Strain : Change in length / original length = No unit Hook's law = good for elastic limit Modulus of elasticity = linear stress/linear strain Poison ratio :  lateral strain / linear strain (Max. = 0.5) E = 210 kN/mm2 Strain roseter = used to measure liner strain. Max. stress at smaller end in tapper bar bolt pass through pipe both are tightly fitted with nut and washer so bolt in tension tube in compression bar cooled at -5 degree c it develop tensile stress. Energy stored in body = strain energy Total strain energy stored in body = Resilience Max. strain energy stored in body = Proof resilience Proof resilience / Unit volume = Modulus of resilience  Strain energy suddenly loaded = 4 x Gradually loaded  Contraflex point = bending moment change sign (overhanging beam)(simply supported beam) Shear force = 0, Bending moment = max Bending moment at fix end = max In pure bending = bending is c...
