Answer:
b = 9.1units
Step-by-step explanation:
Find the diagram attached
Using the similarity theorem of triangle
WX/XZ = WY/WX
Substitute;
b/a+5 = 6/b
b² = 6(a+5) ... 1
Also according to pythagoras theorem on triangle WYX;
b² = 6²+a²...2
Equate 1 and 2
6(a+5) = 6²+a²
6a+30 = 36 + a²
a²-6a+36-30 = 0
a²-6a+6 = 0
a = 6±√36+4(6)/2
a = 6±√60/2
a = 6±7.745/2
a = 13.745/2
a = 6.8725
Recall that
b² = 6²+a²
b² = 36+6.8725²
b² = 83.2313
b = 9.12units
b = 9.1units
Answer:
1500 Time the multiple of model scale is the actual length of the ramp.
Step-by-step explanation:
Given:
Actual length of ramp is 500ft
Modelling scale is 1/125.
To Find:
how many times as long as the actual on ramp is the model.
Solution:
Actual length is 500 ft
When Civil engineer is modelling the ramp on model then it is about 1/125 of the actual length present at that site.
So
=500*1/125
=4 inches
So on model scale engineer took inches as a unit for scale.
Actual length is 500 ft and model length is 4 inches
So 1 ft corresponds to 12 inches hence 500*12=6000 inches
6000 inches corresponds to 4 inches on model scale
i.e it is about 1500 time multiple of the model scale.
