Engineering Mechanics is a branch inspired by examples pertaining to life based problems and solved by the fundamentals of Physics. It deals with forces and moments acting on various systems and also relates the different bodies in action by helping us identify the relationship between their positions, velocities and accelerations. Engineering Mechanics also throws light on various principles like work-energy, impulse-momentum and impact. Mechanics basically uses Newton’s Laws to solve issues and come up with suitable solutions by which activities undertaken get further simplified. From the very beginning mankind used these concepts, then undefined, to solve the issues they faced and reduce the complexity of the problems at hand.

The very first module inspires students by creating an interest within them, of solving complex problems from live examples that relates to their daily activities. Initially the students will be introduced to simple concepts to strengthen up their basics and then they will be introduced to the more complex problems. In this module, the principles of statics are applied to the given force systems thus making the students capable to identify and demonstrate such systems in nature during their day-to-day activities, compare them to other related system of forces and one day design and assemble a system that will reduce benefit society at large.

The second module of this subject introduces the students to concepts of distributed forces and the concept of friction that deals with forces that opposes the motion of a body relative to the other. A body placed on a rough surface, objects or a group of objects placed randomly or a simple mason standing on a ladder, all are examples based on the topics covered in this module.

The third module uses Newton's first law of motion in which the entire system will stay at rest and thus we can calculate the various magnitudes of forces acting on the concerned objects. This module also deals with the basic structural element of buildings termed at beams with are usually laterally loaded and carry heavy loads of different types. The objects that are placed in space, knowing their weights and position vectors one can calculate the values of tensions found and also the range of tensions it can bear without collapsing. Using Varignon’s theorem we can also locate the position of the application of the resultant of forces parallel to each other and loading a common element.

The fourth module of Engineering Mechanics deals with analysis of various types of trusses and frames that are capable of carrying huge amount of loads and safely transferring the same to column members. Huge civil engineering structures work their magic of lasting years of sustenance due to these members created with basic two force elements. Structures like bridges, industrial sheds, electric high tension towers, long stretches of railway station roofs, gigantic cricket stadium structures, all use trusses to transfer loading effectively and remain in position for more than 5-10 decades. This module also heads with cable subject to point loadings and their related applications.

The fifth module, deals with Kinematics of Particle i.e. relating the displacement, velocity and acceleration of a particle without actually considering the forces that are responsible for the motion to occur. The problems in this part of the module deals with particles falling under the action of gravity, moving with uniform or variable acceleration and also describing the motion of a particle in a straight through a-t, v-t and s-t graphs. It also deals with particle that move in a curved path i.e. motions on a Ferris wheel, or a merry-go-round, of bikers on a curved racing track.

The fifth module, deals with Kinetics of Particle i.e. application of Newton’s third law in different real life problems, using the principles of Work-Energy and Impulse-Momentum into basic and complex problems for calculating the unknown values. It also highlights the Momentum conservation principle and concepts of Impact. The students are faced with very interesting problems related to sports, lifts, pulley systems etc. which enhances their motivation to learn the beautiful and dynamic subject, Engineering Mechanics.
