Use a free body diagram to evaluate the situation. What is the tension in each of the ropes attached to the ceiling if the hanging mass is 0.55 kg?
Two ropes are attached to the ceiling carrying the same box. One is tilted at a 30 degree angle and the another is at 45 degrees.
the horizontal component of the forces in the two ropes are equal but opposite in direction (sign).
the vertical components of the forces in the two ropes add to cancel the tension of the lower rope (equal to mg).
