### Summary of Content

The aim of this module is to provide the students the basic knowledge of Mechanical engineering Science and Principles and apply them to the design and analysis of engineering components.

### Syllabus

The teaching syllabus will cover the following areas: Forces: Units and dimensions, Type of forces, vector representation, laws of forces- Lami's theorem, law of triangle, law of polygon, parallelogram law- moment of forces, center of gravity and centroid, moment of inertia of plane figures, parallel axis theorem. Analysis of forces: Resolution, equilibrium conditions, support reactions, pin jointed frames, analysis of fames by method of joints. Introduction to beams and Bending: Introduction to different types of beams and loading. Shear force and bending moment diagram for cantilever and simply supported beams under point load only. Theory of simple bending, neutral axis, bending stress in simple symmetrical sections. Linear motion and Angular motion: Equations of motion, velocity and acceleration, relation between linear and angular motion, Newton's law of motion, momentum Dynamics: Displacements, velocity and acceleration, their relationship, relative motion, rectilinear and curvilinear motions, Newton's law, motion of rigid body, types and their analysis in planar motion, work energy equation of particles, impulse and momentum, impact of elastic bodies. Translation and rotation of rigid bodies, velocity and acceleration, general plane motion. Friction: Types of friction, laws, coefficient of friction, friction on inclined plane Vibration Simple harmonic motion, types of vibration, degree of freedom analysis of frequency for a spring mass system, springs in series, parallel and combined

### Learning Outcomes

On completion of this module the student should be able to:1. Describe the principles of statics and apply in two dimensional force systems. (AM1, AM4, AM8).2. Analyse the forces in members of pin jointed frames (AM1, AM8, AM5) 3. Determine the center of gravity and moment of inertia of plane figures (AM1, AM5)4. Explain the principles of dynamics and apply in two dimensional force systems. (AM1, AM4, AM8)5. Illustrate the basic laws of friction. (AM1, AM4, AM8)6. Identify the types of vibration and frequency for a spring mass system.(AM1))

### Teaching / Learning Strategy

The main teaching method will be based on lectures supported by tutorial sessions. The students will be expected to perform directed reading exercises and self-learning exercises on emerging technologies.
