A drill bit includes one or more cutters on a surface thereon configured to penetrate into a formation, at least one pad at the surface, and an actuation device configured to supply a fluid under pressure to the pad to extend the pad from the surface. The drill bit also includes a relief device configured to drain fluid supplied to the pad to reduce the pressure on the at least one pad when the force applied on the at least one pad exceeds a selected limit.

An earth-boring tool, comprising: a tool body;cutting elements carried by the tool body;at least one movable member disposed at least partially in a recess in an outer surface of the tool body, the at least one movable member configured to move outward and inward relative to the outer surface of the tool body;an actuation unit configured to cause the at least one movable member to move outward relative to the outer surface of the tool body, the actuation unit comprising: a first fluid flow control device in fluid communication with a hydraulic fluid reservoir; anda first fluid line in fluid communication with the first fluid flow control device and a chamber within which the at least one movable member is configured to move;a relief device configured to enable the at least one movable member to move inward relative to the outer surface of the tool body, the relief device comprising: a second fluid flow control device in fluid communication with the hydraulic fluid reservoir;a second fluid line in fluid communication with the second fluid flow control device and the chamber within which the at least one movable member is configured to move; anda third fluid line extending from the second fluid flow control device and the first fluid line of the actuation unit, wherein, when opened, the second fluid control device drains hydraulic fluid from the chamber through both of the second fluid line and the first fluid line to the hydraulic fluid reservoir;a downhole sensor located and configured to generate a signal relating to a downhole measured parameter; anda control unit operatively coupled with the downhole sensor, the actuation unit, and the relief device, the control unit configured to cause the at least one movable member to move relative to the outer surface of the tool body using the actuation unit or the relief device responsive to the signal generated by the downhole sensor. 2. The earth-boring tool of claim 1, wherein the earth-boring tool comprises a bottom hole assembly. 3. The earth-boring tool of claim 2, wherein the tool body comprises a bit body of a drill bit. 4. The earth-boring tool of claim 1, further comprising a biasing member coupled to the at least one movable member and configured to urge the at least one movable member to move inward relative to the outer surface of the tool body. 5. The earth-boring tool of claim 1, wherein the control unit is configured to reduce at least one of torsional fluctuations, lateral fluctuations, rate of penetration, whirl, stick-slip, bending moment, or vibration, by causing selective movement of the at least one movable member. 6. The earth-boring tool of claim 1, wherein the control unit comprises a processor and a data storage device. 7. The earth-boring tool of claim 1, wherein the control unit is configured to automatically and selectively adjust a position of the at least one movable member to control at least one of tool rotation, tool face, pressure, vibration, whirl, bending, or stick-slip. 8. The earth-boring tool of claim 1, wherein the actuation unit is configured to supply hydraulic fluid under pressure to the at least one movable member from a fluid reservoir, and wherein the relief device is configured to transfer the hydraulic fluid supplied to the at least one movable member to the reservoir to reduce the pressure on the at least one movable member when a force applied on the at least one movable member exceeds a threshold limit. 9. A method of forming a wellbore, comprising: advancing an earth-boring tool into a formation, the earth-boring tool including: a tool body;cutting elements;a movable member configured to move outward and inward relative to an outer surface of the tool body;an actuation unit configured to cause the movable member to move outward relative to the outer surface of the tool body, the actuation unit comprising: a first fluid flow control device in fluid communication with a hydraulic reservoir; and;a first fluid line in fluid communication with the first fluid flow control device and a chamber within which the at least one movable member is configured to move;a relief device configured to enable the movable member to move inward relative to the outer surface of the tool body, the relief device comprising: a second fluid flow control device in fluid communication with the hydraulic fluid reservoir;a second fluid line in fluid communication with the second fluid flow control device and the chamber within which the at least one movable member is configured to move; anda third fluid line extending from the second fluid flow control device and the first fluid line of the actuation unit, wherein, when opened, the second fluid control device drains hydraulic fluid from the chamber through both of the second fluid line and the first fluid line to the hydraulic fluid reservoir;a sensor located and configured to generate a signal relating to at least one of tool rotation, tool face, pressure, vibration, whirl, bending, or stick-slip; anda control unit operatively coupled with the sensor, the actuation unit, and the relief device;removing formation material from the formation using the earth-boring tool to form or enlarge the wellbore; andusing the control unit to cause the movable member to move relative to the outer surface of the tool body using the actuation unit or the relief device responsive to a signal generated by the sensor. 10. The method of claim 9, wherein using the control unit to cause the at least one movable member to move relative to the outer surface of the tool body comprises using the control unit to automatically and selectively adjust a position of the movable member to control at least one of tool rotation, tool face, pressure, vibration, whirl, bending, or stick-slip. 11. The method of claim 9, wherein using the control unit to cause the movable member to move comprises using the actuation unit to move the movable member outward relative to the outer surface of the tool body. 12. The method of claim 11, wherein using the actuation unit to move the movable member outward relative to the outer surface of the tool body comprises supplying hydraulic fluid under pressure to the at least one movable member from a fluid reservoir. 13. The method of claim 12, wherein using the control unit to cause the movable member to move further comprises using the relief device to enable the movable member to move inward relative to the outer surface of the tool body. 14. The method of claim 13, wherein using the relief device to enable the movable member to move inward relative to the outer surface of the tool body comprises using the relief device to transfer the hydraulic fluid supplied to the movable member to the reservoir to reduce the pressure on the movable member. 15. The method of claim 13, wherein using the relief device to enable the movable member to move inward relative to the outer surface of the tool body comprises using the relief device to enable a biasing member to move the movable member inward relative to the outer surface of the tool body. 16.
