《建筑力学》试题库 - 湖南工学院精品课程（Construction mechanics, a fine course of hunan institute of technology） The document comes from the network, it is my own collection organized, if have omitted, the error, still asks everyone to correct! The building mechanics test library 1. Fill in the blanks 1. Under any external force Objects that remain constant in size and shape are called Force is the __________________ between objects This effect causes the object to have two mechanical effects: ____________ and ____________ The three elements of 3, Rio is ________________, ________________, _____________ 4. The axiom of the balance force is valid for objects When a rigid body is balanced by the three forces acting on the uneven line, the action line of the three forces will be ______________ The force that causes the object to move or to produce motion is called 7. The direction of the constraint reaction is always in the direction that the constraint can block the motion of the object The restraining force of the soft body is through the force of the 9. The necessary and sufficient geometric conditions for the equilibrium of the horizontal exchange force system are the force polygons 10. The result of the composition of the flat exchange force system is that The magnitude and direction of the resultant force is equal to that of the force in the force The force perpendicular to one axis and the force on the axial projection is ______________ 12, Σ X = 0 means all force on the shaft of the _____ in the system of force projection ________________ is zero 13. The moment of the force pair at any point in the plane is equal to ______________ 14. The algebraic and ______________ of the projection on the coordinate axis 15. The size of the force pairs rotation effect of the object is represented by ______________ The force can be shifted in the same body, but it needs to be attached to a _____________ The moment of force moment is equal to the moment of ___________ 17, at any point in the pla
