Understanding the Effect of Perpendicular Components in Simple Harmonic Motion

AI Thread Summary
In the discussion, the focus is on the effect of perpendicular components in simple harmonic motion (SHM), specifically regarding the velocity components vcosθ and vsinθ. It is clarified that the component vsinθ, being perpendicular to the OY axis, does not influence motion along YOY', leading to confusion about its role in SHM. Participants debate whether the scenario represents circular motion instead of SHM, emphasizing the importance of angular velocity in SHM representation. The mention of missing elements in the provided diagram suggests a need for clearer visual aids to support understanding. Overall, the conversation highlights the relationship between perpendicular components and their impact on motion in SHM.

Homework Statement



Kindly go through the attachment.
(i) vcosθ in a direction parallel to OY.

(ii) vsinθ in the direction perpendicular to OY.

The component vsinθ has no effect along YOY' since it is perpendicular to OY
My doubt is "Why the perpendicularity of vsinθ to OY makes vsinθ to have no effect along YOY'?"

id like to think this is circular motion and not simple harmonic motion.

"Why the perpendicularity of vsinθ to OY makes vsinθ to have no effect along YOY'?"

It does!
 
You can represent SHM with angular velocity. Anyway, i don't see Y' in your picture.
 
Sorry, it is YO
 

Thread 'Errors and significant figures'

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'

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...
