For this feasibility study, we can assume the difference in height between high and low tide is $3$

meters. The platform onto which the clock and generator will be mounted is $2\mathrm{.}5$ meters above mean tide.

The input shaft to the clock is $50$mm diameter requiring a torque of $10$KNm in the clockwise direction. Your design should accommodate the input of energy to the clock when the tide is both rising and falling. How you interface with this shaft should be considered and documented within your work.

Using the material and transmission layout selected by your group in $3)$ above determine the required dimension$($s$)$ for the rack and pinion. You must also include calculation to convince your customer that the forces generated from the rise and fall of the tide will be sufficient to wind the clock
