Problem
A small crate weighing 150 N is suspended from the ceiling by two identical light ropes that are attached to the crate’s top corners and meet the ceiling so that each rope makes an angle of 30° with the vertical. The crate is motionless.
(a) Determine the magnitude of the tension in each rope.
(b) If the crate’s weight is increased to 200 N while all other conditions remain the same, calculate the new tension in each rope and state whether the tension increases linearly with the weight. Explain your reasoning briefly.
