RAnd if you want inline fractions to look bigger, use \dfrac instead of \frac Inline with \frac ##a=\frac{F}{m}## is the acceleration...

Like.
Check your working. I get ##T=\frac{-5a+300}{4}##. I don't know if this is the only mistake. As @kuruman says, the preferred approach... -
RWhy? The original statement of the problem is To @Robeurer : I recommend that you solve the problem algebraically instead of...
-
RThink of it this way. The hanging mass has downward linear acceleration of magnitude ##a_{\text{hanging mass}}.## Every point on the...

RRobeurer replied to the thread A cylinder connected to a hanging mass.So the equation for the torque will be $$TR-f_fR-f_wR=I\alpha$$ $$T-f_f-f_w = \frac{1}{2}Ma$$ From there we can obtain two equations...
-
RRobeurer replied to the thread A cylinder connected to a hanging mass.If the cylinder's acceleration is 0, then the equation for both forces on x and y plane should be like this $$T+f_f-N_w = 0$$...

RRead what I wrote exactly:
-
RThe center of mass of the cylinder is not accelerating, so all the forces on the cylinder must cancel. That would be static friction...

@Robeurer, in addition to what's already been said: Is the rope wound around the cylinder (like a yo-yo) or is the left end of the rope...
-
RThe horizontal forces on it are the friction from the floor, the pull of the rope, and the normal force from the wall. The first two...
-
RRobeurer replied to the thread A cylinder connected to a hanging mass.After re-read the question, the rope is wound around it.
-
RRobeurer replied to the thread A cylinder connected to a hanging mass.I'm not sure either, but maybe it's wound around the cylinder.
-
RRobeurer replied to the thread A cylinder connected to a hanging mass.How come the cylinder is not accelerating? I thought that it will also accelerate just like the falling mass like in the Atwood's...

RRobeurer replied to the thread A cylinder connected to a hanging mass.@Steve4Physics @ibrkic0 I'm really really sorry that it looks like there's a mistake. The question asks about the acceleration of the...
