∙ 14y agoIs this a vertical ladder? Another contributor's answer:Providing that the slide is on level ground and that the ladder is vertical then you have the outline of a right angle triangle with an hypotenuse (the slide) of 3 metres and an adjacent angle of 40 degrees. To find the height of the opposite (the ladder) side of the triangle use the trigonometrical sine ratio: sine = opposite/hypotenuse When the ratio is rearranged: opposite = hypotenuse*sine opposite = 3*sine 40 degrees = 1.928362829 metres So the height of the ladder needs to be nearly 2 metres high.

∙ 14y ago40 Degrees is the most common Angle to set slides at.
The angle of friction is defined as the angle of a plane where a body placed on the plane will start to slide.
By Pythagoras, if the initial height of the ladder is H1 feet, then 252 = H12 + 92 so H12 = 252 - 92 = 544 so that H1 = 23.32 ft. After the move, the base of the ladder is 15 ft from the wall. If the height now is H2 feet, then 252 = H22 + 152 so H22 = 252 - 152 = 400 so that H2 = 20 ft. So the ladder will slide down 3.32 ft or 3 ft 3.9 inches, approx.
Yes.
An example of an inclined plane is a ramp, slanted road, or a slide. An inclined plane is a surface that is at an angle against a horizontal surface.
40 Degrees is the most common Angle to set slides at.
length of the slide= 47.10 feet

You slide it at an angle.
The angle at which loose material will not slide down a slope is called the angle of repose. It is the maximum angle at which an inclined surface formed of a particular loose material can remain stable without sliding. The angle of repose varies depending on the size, shape, and friction of the particles making up the material.
Sin(33.5) = 26/Length so Length = 26/sin(33.5) = 47.1 ft, approx.
This would be the arccos(21/25), which is 32.859880378889108736588042568 degrees! lol
1) angle of rest: 2) The angle between the horizontal and the plane of contact between two bodies when the upper body is just about to slide over the lower. Also known as angle of friction.
you have to use a factor tree
No. if the floor is smooth you must have friction between the ladder and the floor, or the ladder would just slide away. Technically you could do without friction between wall and ladder, but even that can be helpful in preventing the ladder from going sideways.
No, a ladder leaning against a wall is not in equilibrium. Equilibrium would occur if the forces acting on the ladder were balanced, but in reality, the ladder is subject to gravitational force and may slide or topple over if not properly stabilized.
