I believe the answer is:

pile driver

I'm a little stuck... Click here to teach me more about this clue!

'forceful machine' is the definition.
'pile driver' can be an answer for 'machine' (pile driver is a kind of machine). I'm not certain of the 'forceful' bit.

'stacked next to stream' is the wordplay.
'stacked' becomes 'piled' ('pile' can be a synonym of 'stack').
'next to' says to put letters next to each other.
'stream' becomes 'river' (river is a kind of stream).
'piled'+'river'='PILE-DRIVER'

'gets' acts as a link.

Can you help me to learn more?

(Another definition for pile driver that I've seen is " Big shot".)
