Using the NIOSH Lifting Equation, compute all multipliers at the origin and the destination, and then calculate the RWL at both the origin and destination, and finally calculate the LI for this task $($lifting index$)$ and interpret the physical demands. Use the following information:

Record Rack$$ deer blocks weighing thirty pounds are transferred from the conveyor belt to a pallet to be prepared for shipping. To perform the task, the worker $($a $6$ ft tall male weighing $230$ lbs$)$ must pick up the block from the end of the belt and place it on the pallet, to fit as many blocks on the pallet as possible. Each pallet is stacked four rows in length and two rows in height. Each block is $10$ x $10$ x $10$ cm$,$ and the worker is holding the block from the top surface. The worker$$s feet $($midpoint between feet$)$ are $20$ cm from the belt and the pallet. The belt and the pallet are $40$ cm and $30$ cm high. The most extreme destination posture is created $4$ blocks horizontally and two blocks vertically where the spine is inclined at $45$ degrees to horizontal $($Figure $1).$ In an eight$-$hour shift, workers will move approximately $3,000$ deer blocks. Assume $20$ degrees and $75$ degrees of asymmetry at the origin and destination positions. $1$ ft $=0\mathrm{.}305$ m; $1$ lb $=0\mathrm{.}45$ kg
