1.Equate to zero the moment about one point and the force sums in two directions. This is the approach of Eqs.(2a,b).
2.Equate to zero the moment sums about two points and the force sum in a direction that is not perpendicular to the line connecting the two chosen points.
3.Equate to zero the moment sums about three points that are not collinear.
4.A particle will remain at rest or move with constant speed along a straight line, unless it is acted upon by a resultant force.
5.When a resultant force is exerted on a particle, the acceleration of that particle is parallel to the direction of the force and the magnitude of the acceleration is proportional to the magnitude of the force.
6.The force exerted on one particle by another is equal and opposite to the force exerted by the first particle on the second.
7.The motion of a rigid body consists of a superposition of two movements.

6．(1)Equate to zero the moment about one point and the force sums in two directions. This is the approach of Eqs.(2a,b).
对某点的力矩的和，和在俩个方向上力的和等于零
(2) )Equate to zero the moment sums about two points and the force sum in a direction that is not perpendicular to the line connecting the two chosen points.
对两点的力矩的和，和在一个方向上力的和等于零，这个方向与所选的两点的连接不垂直
(3)Equate to zero the moment sums about three points that are not collinear.
对不共线的三点的力矩的和等于零
7．(1)A particle will remain at rest or move with constant speed along a straight line, unless it is acted upon by a resultant force.
一个质点，在没有受到合外力作用时，总保持静止或匀速直线运动状态
(2)When a resultant force is exerted on a particle, the acceleration of that particle is parallel to the direction of the force and the magnitude of the acceleration is proportional to the magnitude of the force.
当一个质点受到合外力作用时，质点加速度的方向与合外力的方向相平行，而且加速度的大小与力的大小成正比
(3)The force exerted on one particle by another is equal and opposite to the force
