For the shown spool-plank arrangement, match each condition with all possible outcomes.
Column-I | Column-II |
(A) m>M, plank-incline friction absent | (P) Plank ascends |
(B) M>m, plank-incline friction absent | (Q) Plank descends |
(C) m=M, plank-incline friction absent | (R) Plank stays stationary |
(D) m=M, plank-incline friction coefficient tanθ | (S) Spool may rotate clockwise |
| (T) Spool may rotate anticlockwise |
Answer:
A-P,S; B-Q,T; C-R,S,T; D-R,S,T
Solution:
Use force balance, torque balance and the no-slip or impulse constraint for the shown system.
After substitution and simplification, the marked answer is A-P,S; B-Q,T; C-R,S,T; D-R,S,T.
