A chain of lenght 1m lying lenghtwise on a fixed table is partially hanging vertically outside the edge of the table . If the coefficient of friction b/w chain and the table is 0.5 the max lenght of the chain that can hang from the table without slipping?
|dw:1346245068780:dw| let the mass per unit length of the chain = m then mass of length x = m*x and it's weight= m*x*g
to find the maximum length...just equate weight of hanging chain= force of friction...because if is the force of friction that will stop chain from slipping and force of friction= u* normal= 0.5* m(1-x)*g
your final equation is \[0.5*m(1-x)g= m*x*g\] hope this helps you :)
@Yahoo! did you get 0.33m
wat would be its mass
you can't calculate mass ...don't worry it will be canceled on both sides
@Yahoo! check out the above equation
oh ...yup.....u explained this....so...well..lol
:)
thxxx a lot
you're welcome
