A man is climbing up a ladder which is resting against a vertical wall. When he was exactly half way up, the ladder started slipping. The path traced by the man is Correct Answer Circle

Concept:

When the man is exactly mid way, the ladder starts slipping.

The path traced by man will be circle.

This is the case of elliptical trammel when the point of consideration is mid point of binary link. This point will trace a circle.

If point P is not at mid point, it will trace a ellipse.

i. 1.0 in from the wall
ii. 1.732 m from the wall
iii. 1.0 m above the floor
iv. 1.732 m above the floor
The correct answer is
A ladder of weight 'w' rests against a smooth vertical wall and rests on rough horizontal ground, the coefficient of friction between the ladder and the ground being $$\frac{1}{4}$$. The maximum angle of inclination of the ladder to the vertical, if a man of weight 'w' is to walk to the top of it safely, is tan-1x, where x is
One end of the ladder is in contact with a wall and the other end is in contact with level ground making an angle of 40° when the foot of the ladder is moved through a distance ‘x’ m away from the wall, the end in contact with wall sides ‘3m’ along the wall and the angle made by the ladder with the level is, now 20°. Then, find the value of x?
