IMU Sensor

Just wondering is it possible to measure a tensile force using an IMU sensor?

No. Use a luggage scale or similar.

Just trying to measure a tensile force that the mitral valve exerts on the papillary muscle. Found a load cell that can measure the tensile force range of 0-10N, however its outside my budget cost and I was wondering could I calculate the force using the accelerator within the IMU using the formula F=ma
