Solution

The correct option is A $\frac{18}{8}$ m
Total length of the timber = $\frac{18}{4}$ m

To get 2 side rails of the ladder, we have to cut $\frac{18}{4}$ into 2 parts.

= $\frac{18}{4} \div$ 2

= $\frac{18}{8}$

Hence, each side rail would be of $\frac{18}{8}$ m.

From 18/4 yd of timber, you have to make two side rails for the ladder. What is the length of each side rail?

The two rails of a railway track never meet, i.e., the distance between the rails remains constant throughout their length. These rails are said to be __ to each other.

The two rails of a railway track never meet, i.e, the distance between the rails remains constant throughout their length. These rails are said to be parallel to each other.

Q. A railway engineer who looks after the maintenance of rails is quite fed up of the extensive maintenance that is required at the hundreds of joints in the rails. The gaps between short sections of rails have to be constantly checked. Also they cause the rail ride to be rough. He wants to design a railroad without these joints. However, he knows that expansion on heating is a fact of life and cannot be done away with.
He thinks of using much longer rails to reduce the number of gaps, and hence the maintenance. However, it is pointed out by a colleague that this would not work because longer rails also meant that the gaps had to be longer. This would make the ride rougher and could also prove to be dangerous–the train could derail at these joints.

Answer these questions.
1. Why would the gaps be longer if longer sections of rails are used?
2. Can you offer a solution that would do away with the gaps?

Q. The two rails of a railway track, insulated from each other, and the ground, are connected to a millivoltmeter. What is the reading of the voltmeter when a train travels at a speed of 18 km

0.2 \times 10^{- 4}

T and the separation between the rails = 1 m.

The correct option is A 188 mTotal length of the timber = 184 m To get 2 side rails of the ladder, we have to cut 184 into 2 parts. = 184 ÷ 2 = 188 Hence, each side rail would be of 188 m.
