CLASSIFICATION OF APPLIED MECHANICS Applied mechanics can be divided into three main parts. Applied Mechanics Rigid Body Mechanics Rigid Body Mechanics Deformable Body Mechanics Deformable Body Mechanics Fluid Mechanics Fluid Mechanics Dynamics Kinematics Kinetics Elasticity Static's Plasticity Viscoelasticity Liquid Gases

Applied Mechanics Applied mechanics or Engineering mechanics or is the science of applying the principles of mechanics. Applied mechanics is concerned with both the analysis and design of mechanical systems.

Mechanics Mechanics - study of physical actions of forcesMechanics - study of physical actions of forces Mechanics is divided intoMechanics is divided into –Statics –Dynamics

Statics The statics is branch the of engineering mechanics which deals with the forces and their effect, while acting upon the bodies at rest.The statics is branch the of engineering mechanics which deals with the forces and their effect, while acting upon the bodies at rest. The study of systems that are in a constant state of motion, whether at rest with no motion or moving at a constant velocity without accelerationThe study of systems that are in a constant state of motion, whether at rest with no motion or moving at a constant velocity without acceleration

Dynamics The Dynamics is branch the of engineering mechanics which deals with the forces and their effect, while acting upon the bodies in motion.The Dynamics is branch the of engineering mechanics which deals with the forces and their effect, while acting upon the bodies in motion. –It us further sub divided into the following two branches. Kinetics.Kinetics. Kinematics.Kinematics.

Kinematics The Kinematics is that branch of dynamics which deals with the bodies in motion without taking into account the forces which are responsible for the motion.The Kinematics is that branch of dynamics which deals with the bodies in motion without taking into account the forces which are responsible for the motion. –Kinematics - description of motion and includes consideration of time, displacement, velocity, acceleration, and space factors of a system‘s motion

Kinetics The study of forces associated with the motion of aThe study of forces associated with the motion of a body. The Kinetics is that branch of dynamics,which deals with the bodies in motion due to application of force.The Kinetics is that branch of dynamics,which deals with the bodies in motion due to application of force.

Biomechanics Biomechanics is science examine the internal and external forces acting on the human and effects to produces the forces.Biomechanics is science examine the internal and external forces acting on the human and effects to produces the forces.
