    If the angle between rod and rope is 65°, then using sin (65°) for the component of rope tension normal to the rod is correct.

    Edit: Sorry about that, I was thinking of cos (25°) which would yield the same as sin (65°).

    Wait so in the above equation using sin 25 would be the correct one?

    NO, use r ft sin 65 , like you did.

    if the angle between the rod and the wire had been 90,
    it would have provided maximum torque possible (not zero).
