MOTION AND POWER TRANSMISSION




Shreya Prasad

, Mechanism :




Arrangement of multiple machine components which undergo
relative motion between eeeh other to
produce desired mechanical

output .




Kinematics :



Relative motion without
, considering force and motion .




Dynamics :


Relative motion considering , forces and motion

Bodies
# \
Rigid Resistant
No deformation on
applying negligible deformation on

force force application
-


crank springs
-




Links '
