The two main branches of mechanics are statics and dynamics. Static mechanics is the study of forces which are required to keep a body in equilibrium. Dynamics is the study of motion itself, and the forces producing it.
Know MoreA practical example of the use of static mechanics is in architecture. It is necessary to determine all of the stresses that load-bearing supports will be subjected to in a structure. Dynamics is further divided into kinetics and kinematics. Kinetics looks at the forces which are connected to motion. Kinematics ignores the forces themselves, in favor of looking at motion only. A practical application of dynamic mechanics is mechanical engineering. The branches of mechanics are divided even further into fields, depending on what materials they are dealing with. For instance, celestial mechanics has to do the astronomical bodies.

A team scores when the ball touches the ground on the opponent's side of the net or the opponent is unable to return the ball to the other side within three contacts.
Full Answer >Auto service technicians, or mechanics, earned an average annual salary of $39,450 as of May 2013, according to the U.S. Bureau of Labor Statistics. The median income was $36,710 per year. Ten percent made $20,920 or less. The top 10 percent made $61,210 or more.
Full Answer >In physics, the parallelogram law is a rule that states that if two vectors are adjacent to one another, then they can be added together head to tail to find the resultant by drawing a line that connects the vector with the free tail to the vector with the free head. The line that connects these vectors is the resultant vector, which also is the diagonal of a parallelogram.
Full Answer >Principal stresses are the maximum and minimum values of the normal stress that acts on an object. Normal stresses are the stress components that act perpendicularly to an imaginary plane on the object.
