Does anyone know how about how much a used spiral staircase would be? It's all metal with a wooden railing.

I have a used spiral staircase that someone wants to buy, but I have no idea what to ask for it. It is all metal except for the railing which is some type of wood. Any direction would be very much appreciated! Thanks!

When an 80.0-kg adult uses a spiral staircase to climb to the second floor of his house, his gravitational pot

When an 80.0-kg adult uses a spiral staircase to climb to the second floor of his house, his gravitational potential energy increases by 1.80 x 103 J. By how much does the potential energy of a 24.0-kg child increase when the child climbs a normal staircase to the second floor?

please help.

Gravitational potential energy = mgh

m = mass
g = gravitational acceleration (~9.8)
h = height above some zero point.

m(adult)gh = 1.80 x 103 J
gh = (1.80 x 103 J)/m(adult)
m(child)gh = (1.80 x 103 J) x m(child)/m(adult)

Can you describe a spiral staircase without using your hands?

Me and my friends were thinking of riddles and this one came up. we all found it impossible, can anybody help?

There is pillar in the centre and the staircase spirals around this central pillar similar a helter-skelter slide

In less than 50 words describe a spiral staircase without using the words ‘spiral’ or ‘staircase’.? In less than 50 words describe a spiral staircase without using the words ‘spiral’ or ‘staircase’.?

You can read about Harry going to Dumbledore's office using the moving spiral staircase.?

In the Harry Potter books you can read about Harry going to Dumbledore's office using the moving spiral staircase, which is like a spiral escalater. How does he get down again?
Allright.

Whenever Harry goes to Dumbledore's office, he steps on the "moving spiral staircase" which takes him up. So it's like a magic spiral escalator. But the story never tells how he gets down again, of course that staircase only goes up, otherwise it would cause problems if two people would attempt to ride it at the same time.
How does one get out of Dumbledore's office?

Maybe, because it is magical, it prevents people from going both up and down at the same time. And if people meet on the stairs, it is because the staircase has been stopped.

I hope you mean if i was actually speaking to someone, because i can't type without using my hands, but if i were to speak the answer these are the words i would say:
Spiral stairs wind around a central pole. They typically have a handrail on the outer side only, and on the inner side just the central pole. A squared spiral stair assumes a square stairwell and expands the steps and railing to a square, resulting in unequal steps (larger where they extend into a corner of the square). A pure spiral assumes a circular stairwell and the steps and handrail are equal and positioned screw-symmetrically. A tight spiral stair with a central pole is very space efficient in the use of floor area. A user of these stairs must take care to not step to close to the central pole as it becomes more likely that one or more steps may be missed, especially when going down. One should always take care to continuously use the handrail so that additional support is available in the event that a step is missed. Using the handrail will also direct the user to the safer outer portion of the treads.

Mgh=1.8 x 103 J
h=(1.8 x 103)/ (80 x 9.8)

for the child
mgh= (24) (9.8) (h)

take the h from above

Gravitational potential energy = mgh = 1.80*10^3J
m = 80
g = 9.81
Thus u can find h.

Now using h, we can solve for the child's potential energy increase.

Potential energy = mgh
m = 24
g = 9.81
h = (we found this value earlier)

*Note: It doesnt matter whether u take the spiral staircase up or the vertical staircase up as the height is still the same.

drop me an email if u still haev trouble
