They say that engineering, in general, is one of the most complex fields of study. And rightly so; a country's main infrastructure depends on its expertise, whether it be... housing, roads and manufacturing of vehicles and machineryAdded to this today is the entire digital ecosystem: automation, robotics, sensors, telecommunications and a long etcetera that demands precision and fast access to data and tools.
We know it's not vital, but a mobile phone in your pocket can be like a Swiss Army knife if you have the right tools. most useful apps for engineersA well-equipped Android smartphone or tablet can help in both phases. design as in the calculation, field verification, project management and even continuous training.
These are applications that could very well save what amounts to a typical engineer's briefcase With tools, all available virtually on a single screen. From unit converters to structural calculators, including modules for thermodynamics, strength of materials, and statistics, there are specific solutions for almost every field: civil, mechanical, electrical, electronic, chemical, naval, or industrial.
