机械工程专业英语第三课力和力矩ForcesandMoments Forces and Moments When a number of bodies are connected together to from a group or system, the forces of action and reaction between any two of the connecting bodies are called constraint forces. These forces constrain the bodies to behave in a...

device for the simultaneous use of the forces of action and reactionPARRINO IGNAZIO
A force is a push or pull that one object exerts on another.It tends to produce motion, and stops or tends to stop motion.Types of forces Nature of forces Contact force The push experienced when two objects are pressed together Weight The gravitational pull of the Earth on an object Fricti...
aWhenever two bodies interact they apply forces of equal size but opposite direction on each other. Every action has an equal and opposite reaction. 每当二个身体交互式他们在彼此应用相等的大小力量,但在方向对面。 每次行动有相等和相反反应。[translate]...
How does Newton's third law of motion relate action and reaction forces? What do each of the fundamental forces do? What is a solid angle in physics? How does the force of gravity between two objects depend on the distance between the objects? What is the use of a force triangle? How...
Answer to: Find the reaction forces at point A (pin) and the tension in cable BC as shown in the figure. By signing up, you'll get thousands of...
To force to act or speak prematurely or unwillingly. in force 1. In full strength; in large numbers: Demonstrators were out in force. 2. In effect; operative: a rule that is no longer in force. [Middle English, from Old French, from Medieval Latin fortia, from neuter pl. of Latin fo...
balance the resultant of the other two only if it is equal, opposite, and collinear with their resultant. 18 18 Thus, it must act through the intersection of their lines of action. It is sometimes very useful in studying the equilibrium of coplanar force systems. 19 19 Two-Force...
In addition, action and reaction forces in a pair don't act on the same object, and when a force is exerted, there is always a reaction force--a force never acts by itself. Additionally, gravity is a force of attraction between objects that is due to their masses. Lastly, the ...
