Let us consider a belt in the form of a beam on pivoting supports with zero bending moments at the outermost sup- ports. The number of supports in the computational diagram varies from five to nine. We adopt computational diagrams with an odd number of supports to simplify the analysis by using symmetry properties. Figure 1 shows a segment with a uniformly distributed load q. Support roller 1 at the center of symmetry is the weighing support roller.

让我们考虑一腰带以一梁在旋转与零弯矩在最外一口港口一起的支持时的形式。 在计算的图解里的支持的数量从5 变化到9。 我们用奇数支持采用计算的图解通过使用对称性特性简化分析。 1 图显示一部分与一均匀分布的负载q.一起支持1在对称中心台称的支持滚柱的滚柱。
