Hello guys , I cant understand how to do question 5 http://www.xtremepapers.me/CIE/Cambridge IGCSE/0625 - Physics/0625_s09_qp_6.pdf

you need the drawing for first part or second?

 

[Ahmooosh]

sorry but i need both , i cant understand the question in the first place...

in the first question.. simply draw a metre rule and the pivot must be pointing on the middle of the ruler and load Q place it at the right of the ruler ..
2nd question.. using a set square.. place it under the ruler to male sure the ruler is horizontal

Good luck

srry i cant give u a diagram but, in the first one u have to draw a straight line on the pivot, which inclines on one side and there should be Load Q on the side which is inclined.

 

[HorsePower]

make sure u draw it accurately with scale. 1 cm for each 10 cm. thats how my teacher told me to do it.

 

[Ahmooosh]

okay wat about the values? how far away should it be ? i really dont understand this question......

 

[HorsePower]

the ruler is 100 cm long in the question. so draw a 10 cm line

 

[Ahmooosh]

okay, so it should it be 5cm to left and 5 to right... then does the size of the load Q matter? as they say they gave clues to its diameter? and then i should draw it on the right , with 3.45 cm to the right of the pivot? does this seem right?

Edit, please tell me if this is right

Bump.

what you've done is right.

thanks alot , what about second question , the mark scheme says nothing about placing blocks ....
please help.

 

[HorsePower]

well, its almost the same but instead of the straight line u have to show the ruler with marks on it and the middle of the load should be on the 84.2 cm mark. dont forget to label too.
