Method of Members
Method of joint is very good if one has to find
the force in each and every member of the
truss provided each of them is a two-force
member.
Truss members are two force members where
a force is acting at each end of the member.

Angular Kinetics: Chapter 13
What is Kinetics?
Kinetics concerns not only velocity and acceleration but
also the accompanying unbalanced forces that cause
the motion.
Kinetics, the study of unbalanced forces causing the
motion, can be analyzed by three me

What is angular kinematics?
It is the angular movement or rotation of a body
without considering the forces that is causing the
motion.
Angular motion of a body is also called the
rotational motion.
