What will be the readings on the scales? To read a scale that's analog, you have to know what weight scale measurements are indicated by the lines. A. So Newtons need to be converted to KGs or LBs. Introduction. Material. 3) the block has a net force equation of: F = W - T - T = ma W - 2T = 0 W = 2T … https://study.com/academy/lesson/how-to-use-a-spring-scale.html IF IT HAS NEWTONS AS UNITS THEN A horizontal spring scale would read 200 N Ordinary scales have KGs or LBs. Here’s how a C major scale looks on a staff … 3,076 0. The C major scale is very important to practice since once you have the C scale down, the other major scales will start to fall into place. When weighing myself I step on the scale and get a reading, then step off and wait for it to read zero again, then step back on and the reading is always 3 pounds lighter. Older-model spring and dial scales may be accurate as little as 13% of the time. To Do and Notice. Because the spring scale measures friction,therefore the measure from the spring scale is equal to the force needed to do something. Digital scales give you a readout showing weight in whole numbers and decimal fractions. Please explain how you arrived at 200N. Spring Scales. T = 98 N (T, the tension, is what the scale will read, correct? Longer lines indicate larger increments. determined from flexibility analysis. Smaller lines are divisions of the larger numbers. This scale reads force in newtons. The spring can also break, causing the scale to fail altogether. Aug 20, 2005 #5 EnumaElish. If the spring is overloaded and worn out, it will skew the scale results, creating an inaccurate reading. A 20-kg fish is weighed with two spring scales, each of negligible weight. The weight is displayed in backlit numbers on a small screen. Each scale will read 20 kg C. The top scale will read 20 kg, and the bottom scale will read 0 kg D. The bottom scale will read 20 kg, and the top scale will read … Homework Helper. Thats where the answer comes from?) Aug 20, 2005 #4 Tide. You can do some interesting investigations of forces using two spring scales. Science Advisor. so I get the tention in the string is 98 for both but I dont know how to combine the two net force equations into a single answer for the balance reading. Have two people each hold one of the two spring scales. Each of the notes of a C major scale corresponds with a white key on your keyboard. ; Hot Load: This refers to the actual load on the spring hanger during operating conditions; Spring Rate/ Stifness: This refers to the spring rate, force per unit length in N/mm, kg/mm, etc. Last edited: Aug 20, 2005. The needle moves to a number or a line between numbers to indicate the weight. Cold Load: This refers to the load on the spring hanger when the system is in standby or non-operating condition. The properties of the individual spring in the scale must be known by the manufacturer, and the scale needs to be routinely checked to confirm that it is accurate. An analog scale has a spring inside it, calibrated to move a dial or needle when weight is put on it. A digital scale uses a power source to turn the force of the weight on it into an electrical signal. Each scale will read 10 kg B.
