A bolt on a car engine is to be tightened with a torque of 35 Newton meters?

Question

If you have a 25 cm long wrench, what force should you exert?
1.4 N
1.4 x 102 N
8.8 N
8.8 x 10-1 N

Can you help me

Answer 1

Well, lets see, that's 35 newton meters, which is equal to roughly 47.5 foot-pounds.

So you would have to exert enough energy to make your torque wrench reach either setting.

Without a torque wrench, it's 2 grunts and a groan to get as close as possible. (each grunt equals 20 foot pounds, or two groans. Each groan is equal to 10 foot pounds) You must grunt or groan as you are turning the wrench, not before or after as that will throw off the torque specs of your calibrated elbow.

Seriously, use a torque wrench to make sure it's right. Too tight and it can break the bolt or whatever you're tightening it into. Too loose and the bolt can come out.

i can help you.


25 lbs.

looks like 117 newtons to me, at the end of a 25 cm wrench



in america we would say "25 lbs on the end of a 1 foot wrench"

no we wouldnt we would say "25 ftlbs"

Answer 3

I did a double take at this.
A newton meter is a meter for measureing newtons with.
A newton metre is a unit of work.

Answer 4

Unfortunately, I can't. I'd just twist the sucker until it was good and tight. I have no use for any number of Newton meters, or any kind of meters for that matter, especially parking meters when I have no change.

Answer 5

Ahh...why don't you just use a torque wrench and set it to 35NM?

Answer 6

140 N * 25cm*1M/100cm = 35 N-M

140 N is the answer!
