Problem
A small frictionless ring of negligible mass is held at rest where three light strings meet in the same vertical plane.
(i) Draw a labelled free-body diagram of the ring.
(ii) String S1 is horizontal and is pulled to the left with a force of 140N. String S2 is pulled to the right making an angle of 40∘ above the horizontal with an unknown tension T. String S3 is vertical and supports a block of mass 12kg hanging below the ring. Calculate the value of T.
(iii) Find the tension transmitted through string S3. (Take g=9.8ms−2.)
