TIA.
In answer to your first question, YES.
In answer to your second question : 130lbs

In answer to your third question
The formula is simple as the answer is in the units ...... ft lbs

Torque Applied = Force x Distance

So, if you weigh 200 lbs and you put all of your weight on a 2 ft bar, then the torque would be 400 ft lbs
