Question

Joe wishes to hang a sign weighing 7.50 × 102 N so that cable A attached to the store makes a
30.0° angle, as shown in Figure 7-16. Cable B is horizontal and attached to an adjoining building. What is the tension in cable B?

Answer 1

The tension in the cable B is 231 N

What do you mean by tension?

Tension can be defined as a force along the length of a medium, especially a force carried by a flexible medium, such as a rope or cable. It can be defined as an action-reaction pair of forces acting at each end of the said elements.

From the above figure ,

Ta sin30 = w / sin30

Ta = 750N / sin 30

Ta = 1500 N

In the same way

Tb - Tacos30

(1500N)cos30

231N

Hence, The tension in the cable B is 231 N
