I wrote:

Bending can occur (on vs. in) the middle frame during operation due to the high temperature of the furnace and [the?] axial strains. An excessive bending can cause the pallet car to be engaged with the underlying structure, (and increase vs. thereby increasing) the force required to rotate the conveyor.

The occur usually comes with "in", but here should I use "on" or "in"? I think, I saw "on" in a related document.

I also don't know to use "and increase" or "thereby increasing" in the second part. I think "and increase" doesn't coney that it is the result of the first sentence. if yes, then what is the structure for "thereby ...ing"? did I use it correctly?

And finally, I wrote "the force required to rotate the conveyor". I maybe could write it as "the required force for rotating the conveyor". are they different? which of these is better?

I yet don't know if "bending" is countable or uncountable or both and if I used the cases correctly!

  • We must ask, what gets bent? The frame? Sep 15 '16 at 10:57
  • You would want to say "to become engaged". Sep 15 '16 at 11:04
  • @Yes the frame of a pallet car may gets bent. the front view of pallet car is like ---------, which turns to __--==--__

The more natural preposition to use is of:

Bending of the middle frame can occur...

Bending is a process like washing, so it is uncountable. You should say

Excessive bending... - without the An

thereby increasing is definitely the better of the two options, as thereby makes it clear that one event a consequence of the other, or simply put increasing.

force required is the correct word order, as the correct meaning is given by a reduction of

...increasing the force [that is] required to rotate the conveyor

  • Thanks, then you mean all processes ( ...ing) are uncountable?!

  • For the first sentence, it is the first time I want to emphasize where bending can occur in a pallet car. But I feel to say, "bending of the middle frame" makes it like an aforementioned subject.

  • Strictly processes, yes. The product of a process may be countable: drawing -> drawings. Also, -ing words that represent movements are countable, like comings and goings or meanderings.

  • I think I understand what you mean, but I really do think that what's being bent has to be next to bending, not next to occur. It's that separation of verb and 'object' that got you into trouble with prepositions, because you felt that occur needed the preposition.

  • The comments to my other question says, and increasing is totally wrong, though only "increasing" or "thereby increasing" works.
