What is Engineering Mechanics?

Engineering mechanics is the branch of applied science which works with the laws and principle of mechanics. Whatever the body we seen around us experiences forces and due the forces experienced by the body they undergo motion. The study of object which is either in motion or at rest because of the forces acting on them is done under mechanics branch.

Why  Study of Engineering Mechanics is Essentials?

Nowadays engineers are inventing a lot of machines and structures. To make a proper planning, design of these machines and structures the knowledge of mechanics is very essential. In order to perform his/her job more efficiently and more precisely the study of this branch is necessary for mechanical engineers. It is the mechanics which is recommended for every branch of engineering to study. Without mechanics the design of anything is not possible. The mechanics is present everywhere where forces exist.

The engineering mechanics is subdivided into two types
  1. Statics
  2. Dynamics

Statics

This branch of mechanics deals with the forces and their effect on the bodies which are at rest. For example: if a block is resting on a ground and if we are studying the forces and their effect on that block, than we are dealing with statics branch of mechanics.

A civil engineer mostly works with statics as they design bridges, buildings, roads etc which cannot move. In civil engineering if something moves, it means it gets failed.

Dynamics

It is the branch of mechanics that deals with forces and their effects on the bodies which are in motion. A mechanical engineer works more with dynamics. As they design mechanisms, machines and things which contains moving parts. They create moving objects like automobiles, airplane etc.
For Example: Study of motion of a car running on road, study of motion of thrown object above the ground etc.

Dynamics is further divided into two types: 
  1. Kinetic
  2. Kinematics

Kinetics

It works with the bodies in motion because of the applied forces. In other words it is the branch which deals with the bodies in motion considering the cause of motion (i.e forces).

Kinematics

This branch deals with the bodies in motion without considering the forces causing the motion. It is used to describe the motion of points, bodies and system of objects without taking the mass of each or the forces which caused that motion. It is used in astrophysics to describe the motion of celestial bodies. In mechanical engineering it used in robotics and biomechanics. It describes the motion of systems which is composed of joined parts such as engine, a robotic arm or the human skeleton.
