A worker must carry 25 kg bags of sand from a packing machine to a dispatch zone (approximately 10 m in distance). When carried upright, the centre of gravity (COG) of the bag is approximately 15 cm from the lumbosacral (LS) joint. The same worker is then tasked with carrying 25 kg bags of feather. The bags are stored in the bottom shelf and the worker must hunch down to pick up the bag. You found that the COG of the bag in this position is approximately 70 cm from the LS joint whereas the COG of the upper body is then located 20 cm from the LS joint. How do you calculate the total compressive force on the spine at L5/S1 if the upper body of the worker is 30 kg and the back muscles act at an average distance of 5 cm from the fulcrum at the L5/S1 junction for the two scenarios above ?

Solution 1: Ergonomic Assessment and Improvement. An ergonomic assessment of Paula's workstation could identify areas where adjustments could be made to reduce strain on her wrists. This could include adjusting the height of the workstation, providing wrist supports, or changing the design of the tools she uses. The strength of this solution is that it directly addresses the physical strain causing Paula's discomfort. However, the weakness is that it may require investment in new equipment or tools, and the effectiveness will depend on the specific changes made. Solution 2: Job Rotation. Paula could be rotated between different tasks more frequently, reducing the amount of time she spends on tasks that strain her wrists. This could also include training other workers to perform the welding and gaging operations, allowing for more flexibility in task assignments. The strength of this solution is that it reduces the repetitive strain on Paula's wrists. The weakness is that it requires…

A washing machine can be operated in different modes. In automatic mode, the washing machine will decide the time of washing and quantity of water to be used for cleaning as per the weight of clothes. Then it will complete the washing after sequence of operations. The user also can decide the washing time and quantity of water to be used. He/she can choose his/her own sequence of operations with which the washing machine will wash the clothes. Identify the phase of the life of a product which is related to the above scenario. a.
