1.A steel cable is attached to a ring on the top of a street light. The weight of the street light is W . The other end of the cable is attached to the side of a tall building. The street light is pulled to one side by a horizontal chain and held stationary above the road. Fig. 1.1 shows the cable at 55° to the vertical. The tension in the cable is 43.6 N. a) A force of size W is produced by adding the tension in the horizontal chain and the tension in the cable as vectors. i) State the direction of the vector sum of these two forces. ii) In the space below, draw to scale a vector diagram to determine . State the scale used. Scale used: …………………………… W = ……………………………. iii) Calculate the mass of the street light. mass = …………………. kg
