The center of gravity of a car is at height \(h\) and the distance between its wheels is \(2a\). What is the maximum speed with which this car can go around a level curve of radius \(r\) without overturning?

You've probably done this question before this... the sort of padaaku robot that you are.

max speed will be when mv^2/R = normal |dw:1443721650350:dw| nai bhai abhi phy me thoda sa prblm hai but how will we use 2a in this case?

wait along with mv^2/r will will also add the torque force right

  • imqwerty
but no i donno anythin abt torque rn nd i can't relate the height and use it in the solution

\[N_i + N_o = mg\tag{1}\]\[f = \frac{mv^2}{r}\tag{2}\]\[N_i (a) + f(h) = N_o (a)\tag{3}\]For overturning, the inner wheel loses contact, so \(N_i = 0\).

The third equation is why torque is so useful.

ok :) got it i'll try to finish it up by sunday :) so no os till then :D

No OS till then? OK :( This is related to rotational mechanics

yea i've suffered in allen cause of phy nd now its time to finish off the back log :( so no os..till sunday (:
