Describe and differentiate between . 11.1 - Torque. Increased Force = Increased Torque. Increased Radius = Increased Torque. 11.1 - . Torque. Only the tangential component of force causes a torque:. 11-1 Torque. This leads to a more general definition of torque:. The height of the top of the block (iceberg, continental crust) would be h. m. ’ + h. c. Response of the crust to a addition of a load (sediment accumulating or a large volcano): the crust “floats” downward to re-establish isostatic equilibrium and the elevation of the crust changes less that the thickness of the material added. . .

Rotation, Torques and The Conditions for Equilibrium. Conditions for Equilibrium. Q: . How do you know when a body is in equilibrium? What two. . distinct kinds of motion can a body have when it is not in “balance”?. J. Klimchuk, NASA-Goddard. When steady coronal heating is concentrated sufficiently low in the legs of loops, no equilibrium exists, and a cyclical behavior ensues.. This often includes the formation of a cold condensation, and TNE has been proposed as the mechanism of prominence formation and coronal rain.. … to change equilibrium states!.

A beam is long, compared to the dimensions of its cross section. It does . not. carry loads in the direction along the length of the beam.. A particle is said to be in . equilibrium . if it remains at rest if originally at rest. , or . has a constant velocity if originally in motion. .. To maintain equilibrium, it is . necessary . to satisfy. . When the rates of the forward and reverse reactions become equal, the concentrations of the reactants and the products remain constant. This is the stage of chemical equilibrium. This equilibrium is . 4 - . 2. Equilibrium of a Rigid Body in Three Dimensions. Six scalar equations are required to express the conditions for the equilibrium of a rigid body in the general three dimensional case..  .
