### Spring balance: what will be the reading? [duplicate]

There are two cases: When the two forces say L (for left) and R (for right) are equal. F=L=R What will be the reading? I know the reading would be F but why? When the two forces are unequal that is L ...

### Trying to understand the tension in a spring with two weights attached [duplicate]

Possible Duplicate: Why I think tension should be twice the force in a tug of war For (A) in this image, I would think the tension should be should be 2mg. However, my book says the weight in (A)...

### Tension when two connected blocks are pulled in opposite directions [duplicate]

Suppose there exist two blocks A and B connected by a massless, inextensible cord. Both A and B have equal masses and are acted upon by equal forces in opposite directions. So, is the tension in the ...

### Tension in a string in equilibrium (Y&F University Physics section 4.5) [duplicate]

I'm currently going through University Physics by Young & Freedman, and there's one paragraph (13th edition, end of section 4.5, page 123), I just can't wrap my head around - why is the tension in ...

### What force does the dynamometer show in this case? [duplicate]

So I came across this picture on facebook My logic says it should show 200N, because you are pulling it with 100N on each side. On the other hand (as one of the facebook comments also stated, also ...

### Tug of War force of tension [duplicate]

There are two people pulling on a rope at both 400 N equally. What is the force of tension on the rope. They are equally centered from each other? I said the tension of the rope is 400 N, because ...

### What should the scale show? [duplicate]

If $g=10 N/kg$ , what will show the Scales? Yes, I know this is a very simple problem. But, I am stuck. $$P=mg \Rightarrow m=\frac{100N+100N}{10N/kg}=20 kg .$$ But, I'm worried about this ...

### Tension in string due to two opposite forces [duplicate]

If you attach a ideal string to a wall and pull it with force F, there should be a tension T=F in the string. And the string will apply force F on the wall too. But what if there are two persons ...

### Tensions in a rope [duplicate]

If two tensions are acting on a rope such that they are equal (each is 10 N) and opposite (180 degrees) then what will be the total tension in the rope? I cant seem to figure out if these two will ...

### Why do you not double calculated tension when there are two tension forces? [duplicate]

So there is a weight acting at the centre of a rope causing two equal tension forces either side of it. I’m having difficulty working out why you do not double the tension calculated at the end. For ...

### Stretch length of horizontal and vertical springs

If the spring in Figure A is stretched a distance d, how far will the spring in Figure B stretch? The spring constants are the same. The answer is "by half". I don't get it, to me it's the same.
If there are two people on ice skates named $A$ and $B$, and $A$ pushes on $B$ with a force $F_A$, then both of them will experience a force of magnitude $F_A$ in opposite directions. I'm confused as ...
