What is the role of maths in engineering?

Answer 1

which field?civil engineering:

must calculate how much strength a straight bar will bear (like a bridge)
before breakage. How much weight can a cable of x amount of strands take before it puls apart.
Electrical engineering: 20 gauge wire can carry x amount of current, with a loss of y over z distance.
How much wire of that size can you lay before you lose too much current for said circuit.

Mathematics is core to every engineering field.
There are a hundreds of applications. for example:
1- modeling and study of electric circuits using mathematical differential equations of first, second and higher orders.
2- the design of system such as filters using Laplace and Z transforms.
3- mechanical applications for motion using special equations.
