15、Can't you see why Iobject toit?(难道你不明白我为什么反对你那样做吗?) 16、For anobject tobe in rotational equilibrium about a certain point, the total torque about this point must be zero.(一个物体若要在某一点处处于转动平衡,在这一点处的总力矩必须为零。) ...
Explain how can an object be in equilibrium if it is moving. Equilibrium: Translational and rotational equilibrium are defined as states where all forces' sum and the sum of all net external torques acting upon a body is zero. The three conditions for equilibrium are: $$\begin{align}\\...
For an object to be in rotational equilibrium about a certain point, the total torque about this point must be zero. 一个物体若要在某一点处处于转动平衡,在这一点处的总力矩必须为零。 Can't you see why I object to it? 难道你不明白我为什么反对你那样做吗? They object to his ethical ...
If an object tried to rotate about an axis other than one passing through its CoM, it would get so out of equilibrium that it would rapidly adjust its rotation to one passing through its CoM. The following experiment (which you can do either for real or in your head) ...

The invention relates to static equilibrium testing apparatus of a machine or a structure part and a method thereof and further relates to measurement of rotational inertia of an object. The invention provides a measuring apparatus of rotational inertia of the object and the method thereof. The ...
Why does an object in motion stay in motion unless acted on by an unbalanced force? Why is the tension force equal to mass x gravity on an inclined plane? Why is applied force upwards for lowering an object? Explai...
Robert E. Johnson, in The Trans-Neptunian Solar System, 2020 6.3 Volatile-supported atmospheres For a TNO with little or no atmosphere, the equilibrium surface temperature, T0, will depend on its rotation rate and thermal inertia (i.e., fast vs. slow rotator), latitude (λ), subsolar ...
In a long straight channel with a circular cross section, the equilibrium position points form a circle with a radius 0.6 times that of the channel cross section. In this section, we describe two major geometric modifications of IMF in detail: channel direction and cross-sectional modifications....
