hey ppl! have just started a course in lagrangian mechanics and it hasnt been the easiest thing. Ahemm, Anywayz we have a assigment to hand in I just don't know how to do these questions. You have to
1. Name cartesian co-ordinates which fully specify the position of all the moving masses in the system.
2. Obtain expressions giving each of the cartesian co-ordinates as functions of the genralised co-ordinates.
]Could any of you show me how to do these 2 and I will try do the rest by myself.]
a. A plastic knife flying through the air
b.A piece of chalk rolling without slipping inside a stationary cardboard roll, but with slippage allowed between the chalk and the board.
Thanx. moo
