City Guilds Model Questions Vol1 2023 Engineering Question 3
Practice practical question 3 from the 2023 City Guilds Model Questions Vol1 Engineering examination. This question covers Mechanical Principles, Simple Machines, Pulley Systems .
A compound pulley system is set up to lift a load. The system consists of a fixed pulley and two movable pulleys arranged such that four rope segments support the load. The load weight is 200 N. During the experiment the following data were recorded: - Effort force measured on the rope: 55 N - When the load is raised by 0.20 m, the effort rope moves through 1.00 m. Using this information: (a) Determine the theoretical mechanical advantage (TMA) of the pulley arrangement. (b) Calculate the actual mechanical advantage (AMA) based on the measured forces. (c) Compute the efficiency of the system as a percentage. (d) Identify two probable sources of error in the experiment and suggest one way to reduce each error.
