Question

Масса одного метра рельса равна 32 кг.Скольно понадобится железнодорожных вагонов грузоподъемностью 60 т,чтобы перевезти все рельсы,необходимые для постройки одноколейно железной дороги длиной 180 км

Answer 1

180 км=180 000 м
На 1 м уходит 32 кг,
 значит на 180 000 м уходит=180 000*32=5 760 000 кг= 5 760 тонн
5 760 тонн: 60 тонн=96 вагонов с грузоподъемностью 60 тонн..
Ответ: 96 вагонов потребуется

Answer 2

Calculation of the Number of Freight Cars Needed

To calculate the number of freight cars needed to transport all the rails required for a single-track railway with a length of 180 km, we need to consider the weight of each rail and the carrying capacity of the freight cars.

Given that the weight of one meter of rail is 32 kg we can calculate the total weight of the rails needed for the 180 km railway as follows:

Total weight of rails = Weight per meter of rail × Length of railway

Total weight of rails = 32 kg/m × 180,000 m = 5,760,000 kg

To convert the weight to metric tons, we divide by 1,000:

Total weight of rails = 5,760,000 kg ÷ 1,000 = 5,760 metric tons

Now, let's consider the carrying capacity of the freight cars. Given that each freight car has a carrying capacity of 60 tons we can calculate the number of freight cars needed as follows:

Number of freight cars = Total weight of rails ÷ Carrying capacity of each freight car

Number of freight cars = 5,760 metric tons ÷ 60 tons = 96 freight cars

Therefore, to transport all the rails required for the construction of a single-track railway with a length of 180 km, you would need approximately 96 freight cars with a carrying capacity of 60 tons each.

Please note that this calculation assumes that the weight of the rails is evenly distributed across the freight cars and does not account for any additional weight from other materials or equipment that may be required for the railway construction.

I hope this helps! Let me know if you have any further questions.
