LAB ACTIVITY

AIM:- To find the limiting force that can be Borne by a string.

MATERIALS REQUIRED:- string balance, weights, light strings, weight hanger.

PROCEDURE:-

Arrange the system as shown in the figure but some small weights like 50 gram on the weight hanger I know the readings of the spring balance. Now, add some more ways to the Hanger and know the readings of the spring balance. do the same tell the string is broken. no the reading of the balance in the following table when the string is broken.

TABLE:-

S.NO | TYPE OF STRING | LIMITING FORCE

1. COPPER. 15 N

2. ZINC. 12 N

3. ALUMINIUM. 8 N

OBSERVATION:- The limiting force of copper is 15 N, zinc is 12 N and Aluminium is 8 N .

CONCLUSION:- The different strings have difference in their limiting forces values.

Answer 2

Answer:

The experiment for the question " conduct an experiment to find the limiting forces that can be borne by different strings "is as under-

Explanation:

Objective- To find the limiting force that can be borne by a string.

Material Required:- Weights, light strings ,string balance, weight hanger.

                                  weights, pan for spring balance, Sand.

Concept : Tension is a constant along the string, equal to the magnitude of the forces applied by the ends of the string.  

If a body is suspended by a string, the gravitational force acts on the body and pull down. But the body does not fall down because it is supported by the string. The supported force in the string which is opposite to the gravitational force is called Tension in the string.

Procedure:

(1)First we have to tie a light string to the fixed support and then tie the other end with the weight hanger consists of 50 g weight.

(2) Add additional 50 g weight to the hanger again and again. And continue the same until the string is broken.

(3) Note down the weight (x) where the string is broken.

(4) Suspend spring balance to a support.

(5) Tie the light string at the end of the balance and at the other end suspend the pan for spring balance.

(6) Now place the weights (x-100 grams) in pan.

(7) Observe the reading in the spring balance.

(8) Add a small amount of sand in the pan by observing the readings.

same is to be done till the string is broken.

(9)now  weight  is to be noted down(W) where the string is broken.

It is the  maximum or the limiting weight that can be beared by the string.

Precautions :

(1) Tie the string carefully so the length of string is same in both situations.

(2) Observe the reading in the balance carefully where the string is broken.

(3) Place the weights in the pan slowly.

Result :

The limiting force of copper is 15 N, zinc is 12 N and Aluminium is 8 N .

Thus, this is the experiment , to find the limiting forces that can be borne by different strings .
