Question

A 1.0 N weight is suspended. In each case, write in the magnitudeof the unknown force.
All masses are at rest here (e.g., they are not bouncing).
1.0 N

1. String with negligible weight
F = ______

2. Spring with negligible weight
F = ______

3. Spring with weight of 1.5 N
F= _______

4. Chain with weight of 2.5 N
F = ______

5. Chain with weight of 0.5 N
F = ______

6. Stretched elastic band with negligible weight.
F =_______

7. Frictionless pulley and string with negligible weight
F =_______

8. Explain how the tension force gets transmitted along from oneend of a string to the other. does the amount of force that getstransmitted depend on how elastic or stretchable the string is?

Explanation / Answer

1. 1 N 2. 1 N 3. 2.5 N 4. 3.5 N 5. 1.5 N 6. 1 N 7. 1 N 8. Tension is effectively internal - it stretches both ways (like arubber band - if you stretch it, it stretches back an equal amount.The amount of tension you feel is exactly the amount of tension theobject puts on the band). The amount of force transmitted does NOTdepend on elasticity.
