Engineering mechanics is the physical science which studies ___________________
______________________________. The subject is usually divided into two parts
namely __________________________ and ___________________________.
Statics. This branch of mechanics studies the ______________________ of bodies under
the action of constant forces and moment, i.e. a body that is either _______________ or
___________________________________________. Examples of static systems include
an aeroplane at cruising speed, a hovering helicopter, a floating stationary ship, etc.
Dynamics. This branch of mechanics studies the ________________________________,
i.e. system where a body is acted upon by an externally applied force which is a function
of time. Examples of dynamic mechanical systems include a grandfather clock pendulum,
a mass-spring system, an accelerating/decelerating vehicle, etc
