Engineering challenges

Where companies and engineers meet to make innovation happen

In ennomotive, we challenge engineers to solve technical problems from leading companies in industries such as automotive, energy, construction, mining and many more. These engineering challenges are described and published on our website so that any engineer from home can brainstorm, submit innovative solutions and win cash prizes and recognition.

Our engineering ecosystem

Ennomotive welcome engineers that enjoy problem solving, who like to stand out from the crowd and get ready to develop new patents or start a new business.

Working on real-life challenges is a very rich exercise that helps engineers train themselves and develop their skills by designing solutions with a clear purpose.

For this purpose, at ennomotive, engineers can find challenges with problem specifications, drawings, pictures, and videos so that everyone can understand what companies are looking for.

Engineers display their talent before companies that value out-of-the-box and creative minds to submit solutions with innovative approaches. The engineers with the best solutions are invited to share their experience through case studies with real engineering cases so others can learn.

Who can participate

More than 20,000 engineers have joined our engineering platform since 2015, a figure that is rapidly growing.

Engineers at ennomotive come from different engineering disciplines, mainly mechanical, industrial, chemical, electric, electronics, and aeronautical engineering.

Ennomotive publishes the top engineering challenge winners, a solvers ranking featuring the professionals that participated and won engineering challenges with their amazing technology solutions.

Question about ’Liner system to cover material heaps’

For the challenge 'Liner system to cover material heaps' I am looking for help to calculate the impact on a rectangular liner of wind gusts of 90km/h up to 120km/h.

Response: A simplified way is to calculate the wind force: F=AxPxCd. F: force; A: projected area; P: wind pressure; Cd: coef.. (2 for flat plate). P=KxdxV^2. K: a-dimensional coefficient =0.5; d: air density=1,25Kg/m 3; V: speed in m/s. This way you can approach
