ESAS 2 Flashcards
What is Engineering Mechanics?
A branch of science that deals with the laws and principles of mechanics
It is divided into two main categories: Statics and Dynamics.
What does Statics study?
The forces and their effects on an object or body at rest
Statics focuses on equilibrium and stationary conditions.
What does Dynamics study?
The forces and their effects on bodies that are in motion
Dynamics is concerned with the behavior of moving bodies.
What are the two branches of Dynamics?
Kinetics and Kinematics
Each branch addresses different aspects of motion and forces.
Define Kinetics.
The branch of dynamics that deals with bodies in motion due to the application of forces
Kinetics involves analyzing forces acting on moving objects.
Define Kinematics.
The branch of dynamics that deals with bodies in motion without knowing the forces responsible for the motion
Kinematics focuses on the motion itself, such as displacement, velocity, and acceleration.
Fill in the blank: Statics deals with _______
bodies at rest
Fill in the blank: Dynamics deals with _______
bodies in motion
True or False: Kinetics involves analyzing forces acting on stationary objects.
False
Kinetics specifically pertains to objects in motion.
True or False: Kinematics requires knowledge of the forces acting on a moving body.
False
Kinematics does not consider the forces affecting the motion.
What is a key focus of Statics?
Equilibrium of forces acting on stationary bodies
What is a key focus of Dynamics?
Motion and the causes of motion
What are concurrent forces?
Forces whose lines of action all pass through a common point
This concept is important in understanding how forces interact at a single point.
What are coplanar forces?
Forces located in one plane
Coplanar forces are essential in analyzing systems where all forces act in a two-dimensional space.
What is the science that describes and predicts the effect on bodies at rest or in motion by forces acting on it?
A. Engineering Mechanics
Engineering Mechanics encompasses both static and dynamic systems.
What term deals with the conditions of equilibrium of rigid bodies acted upon by a balanced system of forces?
A. statics
Statics is crucial for analyzing structures and ensuring they can support loads without movement.
What is the branch of engineering mechanics which refers to the study of rigid body in motion under the action of forces?
Dynamics
Dynamics focuses on the effects of forces on the motion of objects.
What is the branch of engineering mechanics which refers to the study of rigid body in motion without reference to the force that causes the motion?
Kinematics
Kinematics analyzes the motion of objects without considering the forces involved.
What deals with the forces required to produce motion?
Dynamics
Dynamics is concerned with the relationship between motion and the forces affecting that motion.
What refers to physical quantities that have a magnitude and a direction?
Vector quantities
Vector quantities are essential in physics for describing motion and forces.
What is a vector with a magnitude of one and with no unit?
Unit vector
Unit vectors are used to indicate direction without specifying magnitude.
Fill in the blank: The branch of mechanics that focuses on forces is called _______.
Dynamics
True or False: Kinematics is concerned with the forces that cause motion.
False
Kinematics does not consider forces; it only describes motion.
Which of the following is NOT a type of vector quantity?
Scalar quantities
Scalar quantities have only magnitude and no direction.
