If a street light of mass

M

is suspended from the end of a uniform rod of length

L

in different possible patterns as shown in figure, then If a street light of mass M is suspended from the end of a uniform rod of length L in different possible patterns as

If a street light of mass M is suspended from the end of a uniform rod of length L in different possible patterns as

Options

Apattern $A$ is more sturdy
Bpattern $B$ is more sturdy
Cpattern $C$ is more sturdy
Dall will have same sturdiness.

Correct answer

A. pattern $A$ is more sturdy

Step-by-step solution

Pattern

A

is more sturdy because the moment of the tension about the fulcrum is maximum in

A

to counterbalance the moment of

m g

acting from the centre of mass of the rod.
