Solution to problem 1.2.12 from the collection of Kepe O.?. consists in determining the tension of the rope CD, which holds a plate weighing 8 N in balance, provided that the ropes AB and CD are located in a vertical plane and form an angle? = 30°.

To solve the problem it is necessary to apply the laws of equilibrium. Since the plate is in equilibrium, the sum of the forces acting on it must be zero. It is known that the weight of the plate is directed vertically downwards and is equal to 8 N. Thus, the sum of the vertical components of the forces acting on the plate should also be equal to zero.

The tension in the rope AB is directed upward at an angle ? to the horizon, and its vertical component is equal to Tsin(30°). The tension in the rope CD is directed downward, and its vertical component is equal to Tsin(30°). Thus, the sum of the vertical components of the forces is equal to Tsin(30°) - Tsin(30°) - 8 = 0.

From here we get the equation: T = 16 N.

Thus, the tension in the rope CD holding a plate weighing 8 N in equilibrium at an angle ? = 30°, equals 16 N.
