How can I learn to operate machinery like crane or lift truck by reading manuals online? Are there any books, catalogs or PDF files to download? I do not want to learn it professionally, and I do not want to pay for classes.Thank you very much.
i always wondered that myselfbut inside a mirror ball, would the light be forever boucing around inside.
I will depend on the amount of time between when the light stops and the balloon popsThe light intensity will degrade over time.
Just like learning to drive a car, You could figure out which lever does what by reading books, but to actually operate one takes experience and skillYou can't get that from a book.
