.. A uniform ladder of mass 10 kg and length 4 m rests with one end on a smooth horizontal hoor and the other end against a smooth vertical
wall. The ladder is kept in equilibrium, at an angle tan2 to the
horizontal, by a light horizontal string attached to the base of the ladder
and to the base of the wall, at a point vertically below the top of the
ladder. A man of mass 100 kg ascends the ladder.
If the string will break when the tension exceeds 490 N, find how far up
the ladder the man can go before this occurs.
What tension must the string be capable of withstanding if the man is to
reach the top of the ladder?
