we have
4000 × 500
2 × 80√(5002 + (4 × 802)) = 6562202.
In Chapter XIII., Elevation of Exterior Rail,
E = (WV2
32R/W)g,
| and when W = | 50 |
| V = | 20 |
| g = | 5 |
| R = | 2000 |
we have
E = (50 × 400
32 × 2000/50)5 = 0.03
And finally, in the latter part of Chapter XIV., we have the formula
D = √([n(d + c)2]
0.7854)A
B,
| and making n = | 200 |
| d = | 1 |
| c = | 1½ |
| A = | 4 |
| B = | 3 |
