p margin-bottom: 0.08in; We rarely stop to think about the mechanical make-up of the devices we use in our daily lives. Food scales in dieters’ kitchens incorporate a miniature force transducer allowing them to determine dry, liquid, or chopped ingredients in weight, instead of volume, helpful in watching their waistlines. There are many types of force transducers, usually referred to as torque cells (to measure torque) and load cells (to measure force). When an item is placed on the food scale, the weight is initially evenly distributed. Below the flat tray of most digital scales are four slightly raised pegs just inside the corners that are there to distribute the force of the weight evenly. The mechanical make-up of the digital scale then applies the force of the load to at least one end of a force transducer. As the weight is applied, the end of the force transducer tilts downwards, which changes the amount of electrical resistance running through the scale. The mass of this electrical resistance is passed through a converter that changes it from analog to digital and sends it to a little microchip that is in charge of displaying the highly accurate numbers that are seen either in ounces, pounds, or grams. Portion control is just one of the issues involved in weight management. Precise measurement is also needed to let us know our exercise has paid off and you can now squeeze into those skinny jeans. Step onto your bathroom scale, and you’ll be standing on a force transducer beneath the platform, which converts a change in force into a change in voltage. When you kick the scale on, the battery is sending a particular voltage through the circuits of the scale. Weight applied to the top platform triggers a force transducer beneath which alters the voltage and converts it to a weight read out. That read out can affect your entire day depending on what it says, so if you’re feeling heavy, skip the scale to save yourself some grief!
