Which type of ladder is a non self supporting has one section and has a fixed length which is determined by the length of the side of the rails?
step ladder
An extension ladder's distance from the base of a building should be what proportion of it's total extension?
It is not a proportion. There needs to be aroubd a 75 degree angle from the ground to the base. If it is too flat the ladder can slip out from underneath you. If it is too steep you can tip back. There is usually an angle at the bottom of the ladder if that is flat on the ground then that should be the safest angle (75 degrees)
A ladder is leaning against a wall If the angle is between the ground and the ladder at 60 degrees and the wall is 4m how long is the ladder Give exact values?
If the angle between the ladder and the ground is 60 deg, and you know the angle between the ground and the wall is 90 deg, then you have a 30-60-90 degree triangle, which is a common triangle. You should memorize this one. The commonest sides of this right triangle are 4-5-6, with the longest side being the hypoteneuse, in this case the ladder leaning from the ground to the wall. The wall is 4m high, the base of the ladder would be 5m out from the wall, and the length of the ladder is 6m.
Where can a platform ladder be purchased?
A platform ladder replaces traditional scaffolding. It is used for lower level, above ground tasks e.g. second story tasks. A platform ladder consists of two end sets of steps with a fixed platform between them, allowing for one or two persons to work from it. Because many of its uses are suitable for in home use platform ladders can be bought at home improvement stores such as Home Depot or Lowes. They can also be purchased at any industrial outlet that sells or supplies scaffolding.
What weight can a scaffolding right angle coupler take?
6.25 kn
A firefighter places a ladder against a building The ladder forms a 47 angle with the ground What is the measure of the angle between the ladder and the building?
43 degresses
A painter is standing at the base of a ladder that is leaning against the side of a house What angle do the ladder and the house form?
It can be any angle that is more than zero degrees and less than 90 degrees. <><><> It will be an ACUTE angle, and if the ladder is placed properly (1 ft out for each 4 ft up) the angle between wall and ladder will be ABOUT 18 degrees.
What is the safe working angle for a ladder?
Well it depends on what ladder it is some are safe some are not
Walking up a slope is easier than climbing a ladder Why?
The ladder is set at a steeper angle

How long must a ladder be to reach the top of a 20' wall if the ladder and the wall form a 32 degree angle (at the angle)?
Then an angle of 58 degrees will be at the bottom of the ladder. Use trigonometry and the sine ratio: sin = opp/hyp and hyp = opp/sin hyp = 20/sin(58) = 23.58356807 length of ladder = 24 feet to the nearest foot
A ladder that leans against a building makes an angle of 49 degree with the ground and reaches a point on the building 12m above the ground Find the length of the ladder to the nearest meter?
The ladder forms a right angle with the building: the ground and the building forming the right angle and the ladder forming the hypotenuse. If the length of the ladder is L metres, then sin(49) = 12/L So L = 12/sin(49) = 15.9 = 16 metres.
What is the point of having scaffolding during construction?
Scaffolding is like a giant ladder that helps builders work safely and reach high places during construction. It provides a stable platform for workers to stand on while they build or repair buildings. Without scaffolding, it would be very tricky and dangerous for builders to work on tall buildings. So, scaffolding helps keep everyone safe and makes it easier to get the job done properly.
How long must a ladder be to reach the top of a 20' wall if the ladder and the wall form a 32 angle at the top?
