6. Note the situation where the clothes hanging on the line may be too low. If the weight of the clothes does not change, would raising the line create more or less tension, T? To answer this, consider the required vertical component of T, then the horizontal. Why is an angle of 0° impossible? 2021-01-08 Page 15 of 23
