    Statics Vector
AI Thread Summary
The problem discussed revolves around determining the forces required to lift a roller onto tiles, with an emphasis on static equilibrium rather than dynamics. It is clarified that this is a statics question, meaning acceleration and velocity do not need to be considered. The key is to calculate the maximum opposing force at the initial stage of lifting the roller. The necessary force to overcome this opposing force is minimal, just enough to make it zero. Understanding these forces is crucial for solving the problem effectively.

I am not able to figure out how to solve this problem. It does not seem to be a statics problem to me. At what point do we consider the equilibrium. Please Help!

Yes, it is a statics question: you don't have to consider acceleration or velocity.
To lift the roller onto the tiles you only need enough force to match (plus the teeniest bit) the maximum opposing force. In general, that entails calculating the opposing force at each stage in lifting the roller onto the tiles, but I think it's pretty clear the maximum opposing force will be right at the start. So all you need to determine is the push/pull needed to make a certain force become zero... which one?
 
Thanks haruspex

Thread ''splain this hydrostatic paradox in tiny words'

This is (ostensibly) not a trick shot or video*. The scale was balanced before any blue water was added. 550mL of blue water was added to the left side. only 60mL of water needed to be added to the right side to re-balance the scale. Apparently, the scale will balance when the height of the two columns is equal. The left side of the scale only feels the weight of the column above the lower "tail" of the funnel (i.e. 60mL). So where does the weight of the remaining (550-60=) 490mL go...

Thread 'The Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Coulomb gauge implies instantaneous radial electric field?'

Scalar and vector potentials in Coulomb gauge Assume Coulomb gauge so that $$\nabla \cdot \mathbf{A}=0.\tag{1}$$ The scalar potential ##\phi## is described by Poisson's equation $$\nabla^2 \phi = -\frac{\rho}{\varepsilon_0}\tag{2}$$ which has the instantaneous general solution given by $$\phi(\mathbf{r},t)=\frac{1}{4\pi\varepsilon_0}\int \frac{\rho(\mathbf{r}',t)}{|\mathbf{r}-\mathbf{r}'|}d^3r'.\tag{3}$$ In Coulomb gauge the vector potential ##\mathbf{A}## is given by...
