AI Thread Summary
The restoring moment in the discussed diagram must be anti-clockwise because it opposes the boat's clockwise tilt. When the boat tilts clockwise, the restoring moment acts in the opposite direction to stabilize it. If the boat were tilting anti-clockwise, the restoring moment would then be clockwise. The distinction between restoring and overturning moments is crucial, as the latter reinforces the tilt. Understanding these dynamics is essential for analyzing boat stability.

Homework Statement


why the restoring moment in diagram 3-48 must be in anti-clockwise direction ? can't be in clockwise direction ? pls refer to the last photo ( i sketched it) , if the B' is located on the left of the G , teh restoring moment is clockwise, right ?

That's what you get for attaching pages and pages of unsharp hard to read print : I can't even find 3-48 !
 
A restoring moment (as the term is used in this text) is a moment that tends to oppose the tilt of the boat. Since the boat is tilting clockwise, as viewed, a restoring moment is necessarily anticlockwise. As the diagram shows (3-46, not 3-48), when the moment reinforces the tilt it is called an overturning moment.
Your own diagram shows the boat tilting anticlockwise, so yes, in that case a restoring moment would be clockwise.
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
