The helix angle of a screw thread is the angle formed between the thread's helix and a plane perpendicular to the axis of the screw. It is determined by the pitch of the thread (the distance between adjacent threads) and the diameter of the screw. A larger helix angle generally indicates a coarser thread, while a smaller angle corresponds to a finer thread. This angle is crucial for understanding the screw's mechanical properties and performance in applications.

To produce 1 MW of electricity in a 60 MW power plant, the amount of steam required depends on the plant's thermal efficiency and the specific energy content of the steam. Typically, a steam power plant operates at an efficiency of around 30-40%. Assuming an efficiency of 35%, it would require approximately 2,500 to 3,000 kg of steam per hour to generate 1 MW of electricity, although this can vary based on the specific design and operating conditions of the plant.

In the early 1800s, engineer George Stephenson significantly improved steam engine efficiency with his design of the locomotive, particularly the "Locomotion No. 1" in 1825. His innovations included better use of steam pressure and enhanced boiler design, which contributed to the development of railway systems.
