Question

if you cannot exert enough torque turn a stubborn bolt; would more torque we produce if you fastened a lenght of rope to the wrench handle?

Answer 1

In this simple case, the torque is the product of the force and the radius. To double the torque, you can double the radius (the length of the handle) or double the force. The pipe extension increases the radius. You can increase the force by turning the wrench harder, or by attaching the wrench to something stronger than you are. That's how you could use the rope.

Answer 2

No. At best you might give yourself a bit better 'grip' But, if you slide a length of pipe over the wrench handle, **that** will give you extra torque. If it's a long enough piece of pipe, you might even twist the head off of the bolt or break the wrench ☺

Answer 3

You get more torque if you lengthen the handle, A rope would not get you more torque unless you tied the other end to your car. Ha ha

Answer 4

no- you need to extend the length of the wrench handle by putting a length of pipe over the end or interlocking 2 wrenches together

Answer 5

No. But you could use a bolt loosening product. Try WD40 or go to an auto parts store or a hardware store and tell them what you need.
