Q: All types of jack up cranes. How is the maximum lifting torque converted?
Tower crane lifting torque = crane maximum lifting weight * maximum operating range; for example: the maximum lifting weight is 2T*, the maximum operating range of 50 meters =1000KN.m.
Q: please help me solve.. i really don't get itttt
1 horse power = 746 watt. So the work W done by the crane in 15 s is given by W = 8*746*15 J . So the distance, S through which the crane lifted 100 kg, presumably at constant speed is given by 100*9.81*S = 8*746*15 or S = [(8*746*15)/(100*9.81)] = 91.25 m
Q: I want to know how to make the best and easyist paper crane with origami.
find the instructions online...and fold them. crease the folds a lot so it is more crisp...that's about all i can tell you, because i can't give you the instructions.

I think it's a one time deal. You don't have to string them. You have as long as it takes. Look up Sadako Sasaki. She was a 12 year old Japanese girl who tried to fold 1000 cranes while in the hospital in the 1950's. She had A bomb disease, also know as leukemia. She got it because of the bombing of Hiroshima as a baby. She died after only making 650 or so cranes. It's a very good true story though.
