Simple harmonic motion of a spring

AI Thread Summary
The discussion focuses on calculating the angular frequency of a horizontal plank attached to a spring for small oscillations. The relevant formula for angular frequency is provided, w = (mgd/I)^0.5, with the moment of inertia I calculated as I = 1/3 ML^2. Participants are encouraged to derive the force equation and relate it to the behavior of a mass-spring system. There is a reminder to avoid duplicate posts in the forum. The conversation emphasizes the importance of correctly applying physics equations to solve the problem.

I'm not sure what you did here. Start by writing the force equation and comparing it to that for a simple mass on a spring.

Hi myoplex11, Please don't post the same thing more than once.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
