so, i am fairly good in physics, but, i do have a Q. with a torque wrench, does the wrench move force perpendicular on the axial of the pivot point? so, with torq on a bolt, i apply 80lbs exactly 1ft away from the pivot point this means i have loaded the bolt in compression with 80lbs of force? 2nd, anyone know of any DIY's for building a torq measuring apparatus, something that can be hooked into a laptop to capture graphs of the forces being applied. i was thinking of capturing force applied to a Omega LC304 load cell, and, also capture the range of motion applied to the wrench so we can see on a graph the sudden 'click' when the wrench reaches its set point. your thoughts?
