JNTUK R20 B.tech Engineering Mechanics Syllabus Course Objectives :

The students completing this course are expected to understand the concepts of forces and its resolution in different planes, resultant of force system, Forces acting on a body, their free body diagrams using graphical methods.  They are required to understand the concepts of centre of gravity and moments of  inertia  and  their  application,  Analysis  of  frames  and  trusses,  different  types  of  motion,  friction  and application of work – energy method.

JNTUK R20 B.tech Engineering Mechanics Syllabus Course Outcomes :
  • The student should be able to draw free body diagrams for FBDs for particles and rigid bodies in plane and space and problems to solve the unknown forces, orientations and geometric parameters. 
  • He  should  be  able  to  determine  centroid  for  lines,  areas  and  center  of  gravity  for  volumes  and their composites. 
  • He should be able to determine area and mass movement of inertia for composite sections.
