The steam engine significantly impacted mechanical engineering by revolutionizing transportation and production processes.
Explanation:The steam engine is arguably the most impactful invention on mechanical engineering due to its role in revolutionizing transportation and production processes. This invention by James Watt transformed the way goods were manufactured and significantly contributed to the Industrial Revolution.
True or False: Galvanized steel pipe can withstand moderate freezing.
Answer:
True
Explanation:
Older galvanized steel pipes, which have a tendency to freeze, are a bit more forgiving and will likely not burst. They can withstand extreme cold and warm temperatures.

4. The friction point is the point
(a) where the vehicle starts to move.
(b) where you feel the engine turn off.
(c) when you suddenly release the clutch.
(d) none of the above
The friction point is where the vehicle starts to move, marking a crucial moment in manual transmission operation where the engine's power begins transferring to the wheels, overcoming static friction.
Explanation:The question asking about the friction point in the context of vehicle movement pertains to a scenario in driving where precise control of the vehicle's clutch is necessary. The friction point is correctly defined as (a) where the vehicle starts to move. This is because the friction point refers to the moment in the process of engaging the clutch where the engine's power begins to transfer to the wheels, overcoming static friction, and causing the vehicle to start moving. This is a crucial concept in understanding vehicle dynamics and manual transmission operation.
Understanding the friction point is integral to smooth driving and preventing the engine from stalling. It requires a delicate balance between the clutch and the accelerator, which, when mastered, allows for fluid movement from a stationary position. This concept is an essential part of learning to drive, especially for manual transmission vehicles, where the driver manually controls the clutch engagement.
We are used to connect the external devices and power supply to a computer. My anagram is torps
Answer: Ports
Explanation:
Ports are the devices tat is used for connection of input devices and output devices wit computer.Te links created by ports between peripheral and computing system connects devices such as monitors, keyboard,modems , printer speaker s etc.
External devices get plugged into ports which are embedded on motherboard of the computing system to establish peripheral connection.
