§6.1 Angle of elevation and gradient

= Homework

Let's make a good start, doing exercise 1 together.

Now what can we learn from all this?

Homework time, but...

first of all: time for a JOKE!

(It is a rather sick one, so you may ignore it too!)

When you have recovered from 

Time to ...

+ Test and 

+ Train your

+ Intuition !

This is about exercise 6a:

However, there is a mistake in it:

'The gradient of this street is 0.5 '

This is not correct. Up to you to improve on it!

The gradient of Baldwin street is...

1. higher than 0.5
2. between 0.5 and 0.7
3. lower than 0.5
4. between 0.3 and 0.5

The real gradient of Baldwin street is...

0.35  !

So, 6a tells you about Baldwin street in New-Zealand as being the steepest road on earth.

However.... watch this!

Enough about roads, that is....

we move over to:

RAILROADS(!) , exercise 6b !!

Here is 6b:

Where on earth is Stoos?

6b is about

The world's steepest railway track!

It is in Switserland, Stoos. It is a car-free (carefree too?!) Alpine village. Watch!

Homework time.

Finish §6.1,

arriving at the Finish, just like the train in Stoos!
