Question 2 Three cables are joined at the junction ring \( O \) as shown in Figure 2 . It is assumed that the pulley at point \( \mathrm{C} \) is frictionless. If the tension in cable \( \mathrm{OA} \) is \( 700 \mathrm{~N} \), a) Draw the free-body-diagram (see the note below for definition) of the junction ring \( 0 .(3 \) marks) b) Determine the tensions in OB cable. (6 marks) c) Determine the mass \( M \). Use \( g=9.81 \mathrm{~m} / \mathrm{s}^{2} \). (6 marks) Note: Free-body-diagram is a diagrammatic representation of the isolated system/structure that is treated as a single body. This diagram shows all forces applied to the system through contact/interaction with other bodies, which are imagined to be removed.
