2025年1月7日 · One of the older and simpler bathroom scale designs is an arrangement of levers connected to a spring. The spring is further connected with gears to a dial with readings painted on it. The spring is the "force meter".

2021年12月6日 · You can think of the tension in the spring as the force that each little element of the spring applies to the adjacent little elements of spring. If you think about the little element of spring right at the end of the spring, then it's experiencing a force of ##100 \ \mathrm{N}## from the rope and a tension force ##T## from the rest of the spring.

2005年8月19日 · It will not get extended. To get the spring stretched we require force on either end of the spring and both are equal. These balancing forces produce elongation in the spring. In case of vertically suspended spring one force is the weight and the other force is applied by the ceiling, which is equal and opposite.

2006年8月26日 · What the spring scale reads is the tension exerted by its bottom hook (where you hang things that you want to weigh). The first thing to do is to examine all the force on this system (scale + mass) to find out what it's doing. There's an upward force of 10N, and the downward forces of the weight of the scale (2N) plus the weight of the mass (8N).

2010年12月3日 · Aa spring scale does not measure your mass. Take a perfect spring scale to Nome Alaska and then to the Mauna Kea Observatory. Put an object of a known mass, say 100 lbm on the scale, and the scale will register 100.16 pounds in …

2009年10月4日 · Homework Statement You use a spring scale to pull a 1.5 kg object on a horizontal frictionless surface with a constant horizontal force of 1.3 N (according to the scale reading). You use a stopwatch to time how long it takes the object, starting from rest, to cover a distance of 2.7 m. What is...

2005年8月31日 · A pulley is attached to the ceiling. Spring scale A is attached to the wall and a rope runs horizontally form it and over the pulley. The same rope is then attached to a spring scale B. On the other side of scale B hangs a 120 N weight. What are the readings of the two scales A and B? The weights of the scales are negligible. please help

2009年5月31日 · A 3.0 kg object rotates on a circular platform 1.5 m from the center. The tangential velocity of the object is 10.0 m/s. If the mass is attached to a spring scale, what force will the scale read? Homework Equations Sorry I have no idea. The Attempt at a Solution I could not even attempt or figure out, sorry.

2017年5月3日 · It means the current tension force in the spring scale. So, I would say that the "reading" of the scale in this "situation" will be the same in the usual situation where one end of the scale is fixed on a wall. The two situations are equivalent, as you already proved in your analysis; each scale in each situation is in equilibrium.

2012年10月22日 · Can't open the attachment, but assuming a massless frictionless ideal pulley (yes??), the tension in the rope as measured by the scale must be the same on both sides of the pulley. You will need to draw a free body diagram for each mass to identify the forces acting on each, then use Newton's 2nd law on each to get 2 equations to solve for the ...
