绳、杆牵连模型中的加速度关系剖析

Analysis on Acceleration Relationship in Rope and Rod Implicating Model

通常情况下物理教师会告诉学生在求解绳、杆牵连模型中加速度的关联关系时不能类比速度的关联关系，也即虽然沿杆方向速度相等，但是沿杆方向加速度并不相等．鉴于此，详细剖析了绳、杆牵连模型中的加速度关系．

Normally the physics teachers will tell students the relationship not in the solution of relationship of acceleration rope,the analogy model involved rod speed,i.e.although equal along the rod speed direction,but the acceleration along the rod direction are not equal.In view of this,the acceleration relation in the rope and rod interaction model is analyzed in detail.
