The miserly owner of the candy factory purchased 1000 gallons of molasses to fill his main storage tank. But because he was a cheapskate and didn’t spend any money on maintenance, the ancient valve at the bottom of the tank began leaking in the middle of the night. The following morning the factory workers arrived to find a huge mess with molasses all over the floor. The owner instructed the foreman to top off the tank with water, and to turn on the mixing apparatus in the tank to combine the water with the remaining molasses. The following night, the exact same amount of the new molasses/water mixture leaked onto the floor. Again the owner instructed the foreman to top off the tank with water and mix the solution. The factory’s chemist then ran a test and determined that the tank now held a mixture of 50% water and 50% molasses. How much of the contents leaked from the tank each night?

The eccentric director of operations at the puzzle factory has fenced-off four identically shaped ‘work cells’ that completely fill the factory floor. The edges of the work cells fall on the grid pattern shown, and each work cell contains one pneumatically powered machine that uses NITRA™ components and one electrically powered machine that uses IronHorse™ Motors. Can you determine the shape of the work cells?


Enclosing Time

The inept purchasing agent at the puzzle factory bought the wrong subpanel for the control enclosure for their new automation project – and worse, he didn’t buy from Automation Direct! The enclosure accepts a 12” x 12” subpanel, but he bought a 9” x 16” subpanel. When the project manager heard the news, he was dismayed, because he realized that the time it would take to exchange the subpanel with ‘that other vendor’ would delay his project by at least a week. But the technician working on project announced that he knew a way to cut the subpanel into just two pieces and weld them back together to fit in the enclosure. How did he cut the subpanel?
