3. heena

qn?

4. zaphod

its there on the attached link

5. heena

momentum or moment of inertia??

6. zaphod

momentum

7. zaphod

i need to know the perpendicular distance

8. Frank_Shank

heena, moment means torque

9. Callisto

Measure from the picture...

10. Frank_Shank

god job~ Callisto

11. zaphod

from where to where, thats wht i need

12. Callisto

I think... from A to B... not the direct one, but the distance perpendicular to the weight, I think...

13. zaphod

|dw:1337869363517:dw|

14. Callisto

Yes, I think,

15. zaphod

are you sure?

16. shivam_bhalla

Yes . It is write.

17. Frank_Shank

Callisto is right!!

18. shivam_bhalla

*right

19. Callisto

Nope, I'm not sure. I did bad in my physics exam :S I just remember the formula Moment = FxD(perpendicular) So, D should be the horizontal one (counting from the pivot to the force) in this case

20. zaphod

how much did u score for ur exam?

21. Callisto

Don't want to mention it.. I'm sorry... :S

22. shivam_bhalla

Right @Callisto

23. Callisto

BTW, the question is asking moment of the force Moment = Fd⊥ But momentum is another thing momentum = mv ...

24. shivam_bhalla

moment = torque= (perpendicular distance) x (Force)

25. Callisto

So... when heena asked 'momentum or moment of inertia??' it should not be momentum..
