A mechatronics engineer works to automate the transfer of materials and goods, and the manufacturing process. Their tasks involve identifying areas for task automation, designing, developing and testing potential mechatronic devices, and implementing design solutions.
A typical tea bag has somewhere between a gram and two grams of stuff in it. If the entire contents were nothing but fructose, and that fructose completely dissolved when you made your tea, you'd consume between 4 and 8 calories (carbohydrates contain 4 calories per gram) per cup of tea -- so that's the ceiling.
Measure out your tea. If your tea comes in bags, you're all set. For loose tea, you'll need approximately 1 teaspoon per 6 ounce serving of water. Use a teaspoon to measure out the correct amount into your tea bag, tea ball or basket filter. Place it inside the cup, mug or teapot you're using.
