A Butchery at Western Cape requires a modularized trolley designed for 300 Kg maximum load bearing capacity. Before developing the trolley, mechanical engineering design 2A (MDSMIA2) student's made a further enquiry to identify the design criteria. The information obtained is as follows: L The trolley will be shipped to the location using a drone that can lift 20 Kg maximum load II. 300 mm depth. The drone has a standard box compartment measuring 1000 mm length, 600 mm width, and III. The trolley must be detachable or foldable due to storage space during shipping IV. The trolley must have a sealed base. A perforated base will cause drippings through the cavities V. For easy assembly, the components and joints must be fastened using non-permanent fasteners such as bolts & nuts, keys & keyways etc. VI. Standard off the shelf wheels are required for maintainability Referring to standard selection tables/catalogues, design the trolley body, base, mounting platform, and shaft. Based on calculations, select suitable springs, bearings, wheels, fasteners and make logical assumptions where necessary. The design must fulfil the client's design criteria (loading, transportation requirements, size, performance, material). Consider the applicable Young modus and modulus of rigidity. (Assume the square meter weight of most solid flat sheets suitable for the trolley design is 3 Kg/m. Furthermore, assume the following weights for materials that are available off the shelf: Bearings: 200 g/bearing Rubberized wheel: 100 g/wheel Helical springs: 50 g/spring Cylindrical shaft: 20 g/mm diametral volume for 1000 mm length Standard trolley handle: 40 g
