力矩平衡是高考近几年出现的考点,它主要考查力矩概念及力矩平衡条件的应用.解力矩平衡问题一般分以下几步:①明确研究对象:明确是哪一物体绕固定转轴平衡;②进行受力分析:对转动平衡物体进行受力分析,要注意每个力的方向、作用点及力臂,转轴处的 Moment balance is the examination site that has emerged in recent years. It mainly examines the concept of torque and the application of moment balance conditions. The solution to the problem of moment balance is generally divided into the following steps: 1 Clear research object: to determine which object is balanced around the fixed axis; 2 Force analysis: To analyze the force of rotating balanced objects, pay attention to the direction of each force, the point of action and the arm, and the axis of rotation.
