What information in the question indicates that the tension in the string section CB is also 60 N ?
Show that the string sections AC and CB are equally inclined to the horizontal (so that \(\alpha = \beta\) in Fig. 7.1).
Calculate the angle of the string sections AC and CB to the horizontal.
In a different situation the same box is supported by two separate light strings, PC and QC, that are tied to the box at C . There is also a horizontal force of 10 N acting at C . This force and the angles between these strings and the horizontal are shown in Fig. 7.2. The box is in equilibrium.
