rod在物理中的意义
an object with one dimension small in comparison with another(such as a metre or a beam) can be modelled as rod.This means that the mass of the object can be considerdto be distributed along a straight line,A rod has no thickness(it is one-dimensional) and is rigid(it does not bend or buckle)
上面是解释,rod是“刚体”吗?能否大概解释一下这段话的意思~
应该是刚性杆的意思.就是在一维空间里,没有宽度,沿着一条直线的物体.
