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 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'1 x, where x is

Applied Mechanics and Graphic Statics
A square hole is punched out of a circular lamina, the diagonal of the square being the radius of the circle. If ‘r’ is the radius of the circle, the C.G. of the remainder from the corner of the square on the circumference will be

[r (π - 0.5)]/(π + 0.25)

[r (π + 0.25)]/(π + 0.5)

[r (π - 0.25)]/(π - 0.5)

[r (π + 0.25)]/(π - 0.5)

[r (π - 0.5)]/(π + 0.25)

[r (π + 0.25)]/(π + 0.5)

[r (π - 0.25)]/(π - 0.5)

[r (π + 0.25)]/(π - 0.5)
