A. Multiple myeloma is a malignant, clonal disorder of plasma cells that originates in the bone marrow. Itâs a relatively common disorder, accounting for 1% of all malignancies and 10% of all hematologic malignancies in adults.
torsion, n 1. , motion or state of torque in which one end of an anatomical component is twisted about its longitudinal axis as the opposite end is either immobile or moves in the opposite direction.
Torque is the twisting force that tends to cause rotation. The point where the object rotates is known as the axis of rotation. Mathematically torque can be written as T = F * r * sin(theta) , and it has units of Newton-meters.When the sum of all torques acting on an object equals zero it is in rotational equilibrium.hile often heard as an automotive term, torque is actually a general physics term that has many applications. Torque is defined as a twisting force that tends to cause rotation. We call the point where the object rotates the axis of rotation.
