摘要：
In one aspect, a drill bit is disclosed that in one embodiment includes a pad configured to extend and retract from a surface of the drill bit and a force application device configured to extend and retract the pad, wherein the force application device includes a force action member that includes a lever action device configured to extend and retract the pad from the drill bit surface. In another aspect, a method of drilling a wellbore is provided that in one embodiment includes: conveying a drill string having a drill bit at an end thereof, wherein the drill bit includes a pad configured to extend and retract from a surface of the drill bit and a force application device that includes a lever action device configured to extend and retract the pad from the surface of the drill bit; and rotating the drill bit to drill the wellbore.
