Question
If street light of mass M is suspended from the of a uniform rod length L in different possible patterns as shown in figure, then :
Options
A.Pattern A is more study
B.Pattern B is more study
C.Pattern C is more study
D.All will have same sturdiness
Solution
Torque created due to weight of street light remains same in all the three cases. It is balanced by torque created by weight of lamp and T be tension in the string and d be perpen dicular dostance of cable from the axis them,
τ = T.d
Tension will be least for largest d. This is in pattern A. So pattern A is more study.
τ = T.d
Tension will be least for largest d. This is in pattern A. So pattern A is more study.
