You will carry out a series of practical activities using the available apparatus safely, in accordance with relevant risk assessments, to measure the following criteria of simple and complex lifting devices. Mechanical Advantage (MA), Velocity Ratio (VR), Work input, Work output Efficiency You need to record the results systematically. In your report (logbook) you need to include Definition of the simple and complex pulley systems Theory of the test including applied formal and equations Applied apparatus Health and safety risks and hazards (if applied) Observation and record of results (Compete table 1 and 2) Analyse the obtained results by comparing the measured values and those predicted by theory. Evaluate the dynamic parameters and operation of a simple and a complex lifting machine by comparing between measured values and those predicted by theory. A-Simple Pulley System The simple pulley system shows in figure 1 has four pulleys which support the load by dividing it into four lengths. Each part of the rope equally supports the load. You have to lift the load of 16 Kg up to 15 cm from the ground floor. Determine the kinetic and dynamic parameters by completing table 1 and table 2 and considering figures 1 and 2 respectively using experimental and calculation approaches.
