Did you know?
Did you know that the velocity ratio and efficiency of a system of pulleys can greatly affect the amount of effort needed to lift a heavy load? In this particular system, with a velocity ratio of 6 and an efficiency of 80%, the effort required to lift a load of mass 120kg can be calculated. By applying the formula: Efficiency = (load ÷ effort) × 100, we can rearrange it to find the effort. Given the load of 120kg, the effort required using this system would be approximately 90kg. This highlights the importance of understanding the principles and characteristics of pulley systems to optimize efficiency and minimize effort when lifting heavy objects.
