A bar of uniform cross section and weighing 100 N is held horizontally using two massless and inextensible strings S1 and S2 as shown in the figure.
-
- T1 = 100 N and T2 = 0 N
- T1 = 0 N and T2 = 100 N
- T1 = 75 N and T2 = 25 N
- T1 = 25 N and T2 = 75 N
- T1 = 100 N and T2 = 0 N
Correct Option: B
T1 + T2 = 100 N
∑ MA = 0
T2. | = 100 × | |||
2 | 2 |
T2 = 100 N
T1 = 0 N
