5. Mechanics
Branch of science that is concerned with
state of rest or of motion of bodies that are
subjected to action of forces
Rigid body mechanics
Deformable body mechanics
Fluid mechanics
6. Rigid body mechanics
Statics
Dynamics
Statics deals with the equilibrium of bodies that are
either at rest or move with constant velocity:
Dynamics deals with bodies that have accelerated
motion
7.
8. Coarse Contents
1. Review of Newton’s law of motion and vector algebra
2. Equilibrium of bodies: Free-body diagrams, conditions of
equilibrium, torque due to a force, statical determinacy.
3. Plane trusses: Forces in members of a truss by method of joints
and method of sections.
4. Friction: Sliding, belt, screw and rolling.
5. Properties of plane surfaces: First moment of area, centroid,
second moment of area etc.
9. 6. Virtual work: Principle of virtual work, calculation of virtual
displacement and virtual work.
7. Shear Force and Bending Moment Diagrams: Types of load on
beams; classification of beams; axial, shear force and bending
moment diagrams: simply supported, overhung and cantilever
beams subjected to any combination of point loads, uniformly
distributed and varying load and moment.
Experimental project assignment/ Micro project: Students in groups of
4/5 will do project on
Model Bridge Experiment : This will involve construction of a model
bridge using steel wire and wood
16. Course Learning Outcomes
The students will be able to
Determine resultants in plane force systems
Identify and quantify all forces associated with
a static framework
Draw Shear Force Diagram and Bending
Moment Diagram in various kinds of beams
subjected to different kinds of loads
17. NEWTON’S THREE LAWS OF MOTION
First law.
A particle originally at rest or moving in a straight line
with constant velocity, tends to remain in this state
provided, the particle is not subjected to an unbalanced
force
18. Second law.
A particle acted upon by an unbalanced force F
experiences an acceleration a that has the same
direction as that of force and the magnitude that is
directly proportional to force
19. Third Law
The mutual force of action and reaction between two particles are
equal. opposite. and collinear
20. •Particle
It has mass but size that can be neglected
•Rigid bodies
It can be considered to be made up of large number of
particles in which all particles remain at fixed distance from
one another both before and after applying of force
•Deformable bodies
The bodies in which particle to particle distance does not
remain the same and it can go in the plastic zone in which it
can completely change or deform.
21. •Concentrated force- When a force acts on a small area
Concurrent and non concurrent system of forces
•When line of action of all forces pass through a single point
then it is concurrent system of forces
•When line of action of all forces pass through a single point
then it is non concurrent system of forces
