how to read spring scale

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