Can the meterstick platform be in equilibrium if the two upward support forces are equal to each other? If so, give an example from your observations. Can the meterstick platform be in equilibrium if the two upward support forces are unequal? If so, give an example from your observations. Would the platform be in equilibrium if a 500g mass were at the 30cm mark and a 200g mass were at the 60cm mark? Explain. Suppose the 500g mass were placed at the 30cm mark. Where would you place the 200g mass so that both spring scales would have the same reading? Explain. Could you use the same masses to get both scales to have the same reading if the 500g mass were placed at the 20cm mark? If so, where should the 200g mass be placed? If not, why not?

Transcript

00:01 Let's discuss this question.

00:02 So here we have five sub questions.

00:04 Let's see one by one.

00:05 First question says that can the meter strict platform be in equilibrium if the two upward support forces are equal to each other? if so, give an example from your observation.

00:18 Here the second question says, can the meter strict platform be in equilibrium if the two upward support forces are unequal? third question says that would the platform be in equilibrium if a 500 gram mass were at the 30 centimeter mark and the 200 gram mass were at 60 centimeter mark? fourth question is like suppose the 500 gram mass were placed at 30 centimeter mark where would you place the 200 gram mass so that both spring scales would have the same reading.

00:51 And the last question says could you use the same masses to get to get the same? both scales to have the same reading.

00:59 If the 500 gram mass were placed at the 20 centimeter mark, if so, where should the 200 gram mass be placed? so let's see one by one.

01:07 Let's solve the first question.

01:09 So here we can say for the first question that is, can the meter scale platform be in equilibrium if two upward support forces are equal to each other? so here we can say yes, this is possible if two supports forces acting upward are equal then a single force can bring the equilibrium in the system.

02:22 So this is the answer to the first question.

02:24 Now let's see the second one.

02:26 So here it is said that can the metastick platform be in equilibrium if the two upward support forces are unequal? if so, give an example for the observation...
