Measure weight of object hanging from a spring

AI Thread Summary
To measure the weight of an object exceeding 25 N using a spring scale, one effective method involves using a bucket of water to partially submerge the object, which reduces the effective weight measured by the scale. Another suggested approach is to incorporate pulleys, which can distribute the weight and allow the scale to measure a fraction of the total weight. Both techniques utilize commonly available equipment while ensuring the spring scale remains within its limits. These methods provide practical solutions for weighing heavier objects without damaging the scale. Understanding these concepts is essential for effectively applying physics in real-world scenarios.

Homework Statement



A spring that can be considered ideal hangs from a stand. Suppose the spring is used in a spring scale that is limited to a maximum value of 25 N, but you would like to weigh an object of mass M that weighs more than 25 N. YOu must use commonly available equipment and the spring scale to determine the weight of the object without breaking the scale. Show one way that the equipment you choose could be used with the spring scale to determine the weight of the object.

How can you do this?? I'm confused
 
Physics news on Phys.org
you could hang the mass from the spring into a bucket of water
 
I imagine you could also use pulleys.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
