Mechanics Introduction

Question 1

What is the science concerned with the motion of bodies under the action of forces, including the special case in which a body remains at rest?

Answer 1

Mechanics

Question 2

Statics Definition

Answer 2

The study of bodies and structures that are in equilibrium. For a body to be in equilibrium, there must be no net force acting on it.

Question 3

Dynamics definition

Answer 3

is the subdivision of mechanics that is concerned with the motion of material objects in relation to the physical factors that affect them: force, mass, momentum, energy.

Question 4

Branches of dynamics

Answer 4

Kinematics and Kinetics

Question 5

What is kinematics

Answer 5

concerned with the geometric, a possible motion of a body or system of bodies without consideration of the forces involved (i.e., causes and effects of the motion).

Question 6

What is kinetics

Answer 6

concerns The affect of forces and torques on the motion of bodies having mass.

Question 7

Newton conversion

Answer 7

1 N = 1 kg - m/s^2
= 0.22481 lb f
