SUMMARY
A uniform rod of length L, when sliding down a frictionless wall, loses contact with the wall at two-thirds of its original height. The critical angle at which this occurs can be calculated, demonstrating that the sine of this angle is 2/3. This conclusion is derived from the principles of physics governing the motion of rigid bodies and the geometry of the situation.
