OBJECTIVES:

  • To develop capacity to predict the effect of force and motion in the course of carrying out  the design functions of engineering.

Introduction – Units and Dimensions – Laws of Mechanics – Lami’s theorem, Parallelogram and triangular Law of forces –– Vectorial representation of forces – Vector operations of forces -additions, subtraction, dot product, cross product – Coplanar Forces – rectangular components – Equilibrium of a particle – Forces in space – Equilibrium of a particle in space – Equivalent systems of forces – Principle of transmissibility .

 

UNIT II            EQUILIBRIUM OF RIGID BODIES                                                                               12

Free body diagram – Types of supports –Action and reaction forces –stable equilibrium – Moments and Couples – Moment of a force about a point and about an axis – Vectorial representation of moments and couples – Scalar components of a moment – Varignon’s theorem – Single equivalent force -Equilibrium of Rigid bodies in two dimensions – Equilibrium of Rigid bodies in three dimensions

 

UNIT III           PROPERTIES OF SURFACES AND SOLIDS                                                             12

Centroids   and centre of mass– Centroids of lines and  areas - Rectangular, circular, triangular  areas by integration – T section, I section, - Angle section, Hollow section by using standard formula – Theorems of Pappus - Area moments of inertia of   plane areas – Rectangular, circular, triangular areas by integration – T section, I section, Angle section, Hollow section by using standard formula – Parallel axis theorem and perpendicular axis theorem –Principal moments of inertia of plane areas – Principal axes of inertia-Mass moment of inertia –mass moment of inertia for prismatic, cylindrical and spherical solids from first principle – Relation to area moments of inertia.

 

UNIT IV          DYNAMICS OF PARTICLES                                                                                        12

Displacements, Velocity and acceleration, their relationship – Relative motion – Curvilinear motion - Newton’s laws of motion – Work Energy Equation– Impulse and Momentum – Impact of elastic bodies.

 

UNIT V           FRICTION AND ELEMENTS OF RIGID BODY DYNAMICS                                        12

Friction force – Laws of sliding friction – equilibrium analysis of simple systems with sliding friction – wedge  friction-.  Rolling  resistance  -Translation  and  Rotation  of  Rigid  Bodies  –  Velocity  and acceleration – General Plane motion of simple rigid bodies such as cylinder, disc/wheel and sphere.

TOTAL : 60 PERIODS

OUTCOMES:

  • ability to explain the differential principles applies to solve engineering problems dealing with force, displacement, velocity and acceleration.
  • ability to analyse the forces in any structures.
  • ability to solve rigid body subjected to dynamic forces.
