Course Outcomes

Upon completion of this course, students should be able to:

CO1    Explain the basic concepts and fundamental principles in dynamics of particles and rigid bodies. [PO1, LO1, SS1]{C2}.

CO2    Analyze the kinematics and kinetics of particles and rigid bodies problems. [PO2, LO3, SS1]{C4}.

CO3    Evaluate the kinematics and kinetics of particles and rigid bodies involved in dynamical system. [PO3, LO3, SS1] {C6}.

Course Description

The course covers both kinematics and kinetics of particles and rigid bodies in planar and spatial motion. The course emphasizes the use of both scalar and vector approaches for solving particles and rigid bodies dynamics in 2D and 3D, respectively
