Homework

[mattfb]

Had a maths test today. An assessment task they called it. Wasn't all that hard, hoping I did good.

Also had an assessment task in English. Had to write a letter to the Chief Justice of NSW in class. Wrote about 2 pages, and I thought it was decent enough.

We are writing screenplays/script. And i have to do a freaking divorce scene. How am I suppose to do that!?!?
Some 1 help! Tell me how a divorce works, what happens during a divorce, who's there, where are they, what do they do, what do they speak! I need a lawyer!!! Wait, lawyer right? Or some 1 else?

see i have 0 idea about this

Got a stupid Science project, more like an Engineering one IMO
We have to create a machine that lifts 250 grams to a height of 10cm and we have to combine 2 simple machines to make it. Right now i'm thinkin about combinin a pulley and a ram, maybe a lever later on and just make a simple machine, ideas would help

Have a history essay; which is "did ivor williams(soldier, who got shot in the arm once and had a bullet go through the top of his hat etc and served from 1915-1918 so saw WW1 fully)/John monash(very very famous commander WW1, even a university is named after him) have a good war?

That was all a bit messy but I still want you to read it so it stands "did ivor williams/John monash have a good war"?

I am all a bit confused with a question. How the fling can you have a good war?

Colin could you help me out?

He survived so yes.

I have my AP World History exam tomorrow. Should probably go study...

Need to go over some of the Chinese dynasties and what they did a fair bit. And I haven't covered much of the stuff in general from 1914 (start of WWI) - Present...

every 1is asking for help. no 1 is helping

What do you mean by "combine 2 simple machines"?

I would just make a mechanism out of a large and small pulley, with a handle on the smaller one and a rigid platform connected with some wire.

 

[MaD]

Simple machines like inclined plane/ramp, levers, pulleys, wheel and axle etc
We have to combine 2 simple machines and there has to be a good mechanical advantage

Your one actually looks pretty good, a lever and a pulley, don't really get the bottom pic

I'm having trouble figuring out what string i'm gonna use, I was thinking Copper wire or somethin and the machine also has to be able to have a spring balance attached

Also, how com there are pulleys on both sides, wouldn't the weight only be attached to one side? and not really sure how i would make the smaller pulley and attach it to the side and still make it be able to turn

We're not allowed to use any commercial equipment either

Thanks a lot for the help

I have 2 pulleys there so that it doesn't bend the joint. It also provides stability for the seat.

You can see that 2 wires are connected to the seat (the bottom pic), this arrangement makes it so that the seat can't tip over.

I am not sure how the bottom pulley is supposed to be connected either, lol. You might have to make 2 pulleys there as well, connect them through the block with a shaft.

For the wire a nylon string is enough, they are really strong. 250g isn't heavy anyway. I suggest you to not use copper or steel wire, they can't bend easily.

What do you mean by a spring balance?

 

[MaD]

this (spring balance) will be hooked to the end of the string and then the 250g mass will be hooked to that. Yeah, good idea, i'll use nylon string
I reckon a ramp with a pulley would be easier, something like this:



Although which would have a better MA?

 

[TumTum]

That looks even easier. Is there a criteria for this?

 

[MaD]

Nah, just gotta combine 2 simple machines to make 1 lifting machine

Can some 1 post 2 sports articles with Social Commentary and 1 with Science Articles

homework sucks.
Research projects or essays would be alright I guess (which I don't get to do), but doing assignments is a really annoying task.
