Methods, computer programs, and systems for detecting at least one downhole condition are disclosed. Forces are measured at a plurality of locations along the drillstring. The drillstring includes a drillpipe. At least one of the forces is measured along the drillpipe. At least one downhole condition is detected based, at least in part, on at least one measured force. 135-. (canceled)3656-. (canceled)57. A method of analyzing one or more downhole properties , comprising:receiving a plurality of measurements selected from the group consisting of force measurements, pressure measurements, acceleration measurements, and temperature measurements, wherein each of the measurements corresponds to a location along a drillstring, the drillstring comprising a drillpipe, and where at least one measurement corresponds to a location along the drillpipe;determining whether an influx has occurred, based, at least in part, on the plurality of measurements.58. The method of claim 57 , further comprising:determining the location of the influx.59. The method of claim 58 , further comprising:providing a graphical indication to an operator of the location of the influx.60. The method of claim 57 , further comprising:characterizing the influx.61. The method of claim 57 , further comprising:prompting an operator to take an action based on the influx.62. The method of claim 57 , further comprising:taking an action in response to the influx, including shutting in a borehole.63. The method of claim 57 , further comprising:taking an action in response to the influx, including adjusting a mud property.64. The method of claim 57 , further comprising:taking an action in response to the influx, including adjusting a mud flow rate.65. A measurement-while-drilling system claim 57 , comprising:a plurality of sensors to measure a plurality of measurements selected from the group consisting of forces, pressures, accelerations, and temperatures, wherein the sensors are along a drillstring, wherein at ...
