In this paper, we analyze the advanced Feynman’s mechanism from the well-known Feynman’s Lectures on Physics, under the maximum power output, maximum efficient power, and maximum power density criterion. Considering this mechanism like a thermal engine, and using a simplified model, the physical existence regions for these objective functions are shown. We also show their comparison for given values of a defined dimensionless parameter. The behavior for each case of both the general and the normalized forms of the objective functions is compared graphically and the existence of certain intervals of values for the variable parameter used, in which the relation of these objective functions change, is determined. Additionally, it is shown that as the numerical value of the mentioned variable parameter used approaches zero, the area of the region of physical existence of the objective functions is greater. The results of the mentioned comparison are discussed, and appropriate conclusions are included.

考虑不同发电形式的费曼托盘和棘轮机构的简化分析

在本文中，我们在最大功率输出、最大有效功率和最大功率密度准则下分析了著名的费曼物理讲义中的先进费曼机制。将这种机制视为热机，并使用简化模型，显示了这些目标函数的物理存在区域。我们还展示了它们对定义的无量纲参数的给定值的比较。以图形方式比较目标函数的一般形式和规范化形式的每种情况下的行为，并确定所用可变参数值的某些区间的存在，其中这些目标函数的关系发生变化。此外，结果表明，随着所使用的上述可变参数的数值接近零，目标函数物理存在区域的面积更大。讨论了上述比较的结果，并包含了适当的结论。
