Chapter 1 Basic knowledge of statics
Generally speaking, an object is always subjected to many forces at the same time. For example, the floor of a building should not only bear its own weight, but also bear the weight of people, equipment or furniture. Usually we call a set of forces acting on an object a force system.
Under the action of force system, an object is said to be in equilibrium as long as it is at rest or moving in a straight line at a constant speed relative to the ground. For example, buildings such as houses and bridges, as well as elevators that rise and fall at a constant speed, are in a state of balance.
Statics is a science that studies the equilibrium law of objects under the action of force system. Statics mainly studies two basic problems:
The simplification of (1) force system is to simplify the complex force system acting on an object into a simple force system with the same function as the original force system.
(2) The equilibrium condition of force system is to study what conditions the force system acting on an object must meet when it is in equilibrium.
Section 1 Basic Concepts of Statics
First, the concept of force.
Force is the interaction between objects. Without objects, force cannot exist alone. Moreover, there must be a stressed body if there is a stressed body. For example, on the construction site, when we push the car or bend the steel bar, our hands exert a force on the car or the steel bar. Our hands are applied force objects, and cars and steel bars are stressed.
Generally speaking, the modes of force are divided into two categories: one is that two objects contact each other, which is called contact force, such as the pressure of equipment on the floor; The other is non-contact, called non-contact force, such as the gravity (gravity) of an object.
Under the action of force, an object may have the following effects: First, it changes the motion state of the object, which is called external effect or motion effect. Such as a car that moves a car; The second is to change the shape of an object, which is called internal effect. Any object will deform under the action of force. However, in engineering practice, the deformation of many objects (such as beams and columns in buildings) is very small, which has little influence on the study of object balance and can be ignored. An object whose shape and size remain unchanged under any external force is called a rigid body. The object of statics research refers to a rigid body.
