Jap Food...

I went to eat Japanese food at Clementi centre for my lunch before I head for school.What is the shop name I forgot,but I know that it is the kind of cheap food stall.But before that,planned to go Catholic High to deliver letter but there was nobody to come to me as all was in the mist of exam.
I ordered a Curry Udon and a plate of Gyoza and it cost $6.10 with GST.That was like 60% of my yesterday winnings.
Head for school after that.Firstly was Mechanics lecture den Mechanics lab.During the lab,the teacher posted 1 question which kill really lots of my cells.I am sure I am the only 1 doing the thinking so much.Question was,does the height of the load and effort from the ground affect the result on the crab winch?If yes/no,why?Explain in terms of Energy Conservation Principle.
I as thinking about this question when I am on the way home.Kills really lots of my cells on the bus,where I think I have found the answer to it.
