crow's foot should be calculated for a desired torque setting using a
I fully understand how to calculate the torque setting for a torque
wrench when using an adapter, but doing the same for a torque screwdriver
is a bit more challenging.
For instance, the maintenance manual for an aircraft engine states a
torque value of 12 in.lb on a fuel injector B-nut that is difficult to
reach, requiring the use of a crow's foot that has a 1 in. reach. My
smallest torque wrench has a range of 15-100 in.lb. so it can't be used,
but my torque screwdriver is 5-36 in.lb.
How do I calculate the tool torque value that will let me deliver 12
in.lb. using a 1 in crow's foot with a torquing screwdriver, please?
