Torque on a Bolt

What is the required force on a wrench at an angle phi if the bolt comes loose with a force of 33 Nm?

Damn I love this guy. Everytime I search for answers on youtube he appears!

Referred this question to my engineering expert, and this is what he said:

Greetings,
You need to define the term “over torque”
 
Condition 1
The torque specs that are set to achieve a controlled condition. i.e, sealing a flange without distorting or not loosening under vibration or other functional performance.
 
Condition2
The maximum specs for a given screw, determined by size thread schedule and materials,
 
Violate condition 1, You are within the allowable limits of the screw, but have exceeded the limits of mating parts, Mating parts may fail.
 
Violate condition 2 You exceed the limits of the screw, Screw may fail.  Failure can be stretching snapping galling stripping. A screw that has been over torqued, is damaged and will not preform as designed and  therefore should be discarded.
 
 Cheers,
Dr. A

Wonderful lecturer that makes physics fun and understandable !!!

Nice presentation. For the learning glass, are your writing backwards? Or does it have a mirror? Really neat.

Owner of the world's only pentagonal bolt.

Kidding aside, useful.

If you over torque a bolt, lets say a bracket or some other non torque critical item on an object that has vibration and heat, like an engine, but the torque on the bolt doesnt pull threads, what are the odds of loosening, or snapping, or causing damage to the threads from expansion and contraction with the vibrations.

Thanks for your time and efforts. Liked your video. What are you writing on by the way?

love that screen, how did you do that?

Lol! Maybe so I can ask 4, 000$ for an oil change, just make it appear impossibly difficult. Wtf am i watching anyway?
