No. many people are not very good at writing but have successful careers in engineering
Engineering is generally a problem solving profession with math skills. To become a professional engineer, though, the advancement in the field may require writing skills.
Don't see why not.
Yes. If you are professionaly trained for both terms of engineering, there is a possibility that you can.
Yes, it is good choice. But also an engineer need some writing ability.
If you pass all of the schooling to be a Mechanical Engineer (BSc in Mechanical Engineering) Then you may practice Mechanical Engineering as an engineer. Other wise you cannot and should not be expected to be referred to as an Engineer. Additional comments: Depending on the work you are doing, you may also have to obtain a license or certification such as the Professional Engineer (PE) in the USA. If you can pass the tests and perform the work, you can work as a mechanical engineer - HOWEVER - if you are a terrible writer, you may find it difficult to do the necessary work and gain the requisite years of experience. A typical engineer will spend perhaps 1/3 of their time doing "engineering", i.e. design, calculation, testing, building, etc., 1/3 of their time writing reports, memos, etc, and 1/3 of their time in oral communication - making presentations, staff meetings, supervising, talking with vendors, etc. If one is terrible at writing, they will find it difficult to do all that is expected of a practicing engineer.
it will be unwise to think that engineering is for good mathematicians who cant write essays, some are great writers it depend from individual to individual
No, it is not true. It is false.
Excellent writing is when someone has written something excellent. To write something excellent, the writer used their imagination and creativity.
