Summary:An apparatus and method for determining forces on a downhole drilling tool is provided. The downhole tool is provided with a drill collar operatively connectable to the drilling tool, and a sensor mounted about the drill collar. The sensor is adapted to measure deformation of the drill collar whereby forces on the drilling tool are determined. The sensor may be part of a force measurement system, a strain gauge system or a drilling jar system. The drill collar is adapted to magnify and/or isolate the deformation applied to the drill string.
