Which statement best describes the relationship between snatch block tension and rope angle when the angle is reduced?

When a snatch block is used to redirect a pull, the two rope legs share the load, and how effectively that load is shared depends on the angle between the legs. If the angle is large, the two legs can contribute more effectively to lifting the load with a given tension. If you reduce that angle, the legs work less efficiently together, so you have to apply more tension to achieve the same lifting effort. In other words, narrowing the angle reduces the system’s mechanical advantage and the rope tension must rise to produce the same lift. In real setups, friction and equipment limits can make this effect more pronounced, so small changes in angle can lead to noticeably higher tension.
