Pro Tips for Choosing Your Topic

• Replace 'nominal' verbs like 'conduct an investigation' with 'investigate' to increase the density of your engineering arguments.
• Eliminate 'it is' and 'there are' placeholders to ensure the technical subject of the sentence remains the primary focus.
• Quantify vague descriptors like 'vibration was high' by specifying 'vibration exceeded the 5mm/s threshold defined by ISO 10816'.
• Use the active voice when describing the functions of a component (e.g., 'The valve regulates flow') but use the passive voice when describing experimental procedures.
• Ensure that every sentence follows the 'Given-New' contract, placing familiar technical concepts at the start and new experimental data at the end.
