the dark of a force about a point is defined as torque is equal to the radius cross Force suppose radius force and torque rr-90 is a radius call crosstalk parallel to force always to is it ever true 7. The torque of a force F about a point ig defined as r • r x F. Suppose r, F and are ali nonzero. Is r x F always true ? Is it ever true ?
