Here’s how a C major scale looks on a staff … Each of the notes of a C major scale corresponds with a white key on your keyboard. 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 … 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. So Newtons need to be converted to KGs or LBs. … You can do some interesting investigations of forces using two spring scales. determined from flexibility analysis. To read a scale that's analog, you have to know what weight scale measurements are indicated by the lines. Cold Load: This refers to the load on the spring hanger when the system is in standby or non-operating condition. Aug 20, 2005 #4 Tide. What will be the readings on the scales? The needle moves to a number or a line between numbers to indicate the weight. A 20-kg fish is weighed with two spring scales, each of negligible weight. Last edited: Aug 20, 2005. Please explain how you arrived at 200N. Spring Scales. 3,076 0. Science Advisor. 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. Older-model spring and dial scales may be accurate as little as 13% of the time. IF IT HAS NEWTONS AS UNITS THEN A horizontal spring scale would read 200 N Ordinary scales have KGs or LBs. Because the spring scale measures friction,therefore the measure from the spring scale is equal to the force needed to do something. A digital scale uses a power source to turn the force of the weight on it into an electrical signal. 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. A. Each scale will read 10 kg B. ; 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. Homework Helper. Digital scales give you a readout showing weight in whole numbers and decimal fractions. Have two people each hold one of the two spring scales. https://study.com/academy/lesson/how-to-use-a-spring-scale.html Introduction. If the spring is overloaded and worn out, it will skew the scale results, creating an inaccurate reading. Thats where the answer comes from?) The weight is displayed in backlit numbers on a small screen. Aug 20, 2005 #5 EnumaElish. This scale reads force in newtons. The spring can also break, causing the scale to fail altogether. 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. Smaller lines are divisions of the larger numbers. To Do and Notice. An analog scale has a spring inside it, calibrated to move a dial or needle when weight is put on it. 3) the block has a net force equation of: F = W - T - T = ma W - 2T = 0 W = 2T T = 98 N (T, the tension, is what the scale will read, correct?
