This equation is: moment force = F sin (x) r, where F is the applied force, x is the angle between the force... WebDefinition 3.8.1. The rth moment of a random variable X is given by. E[Xr]. The rth central moment of a random variable X is given by. E[(X − μ)r], where μ = E[X]. Note that the expected value of a random variable is given by the first moment, i.e., when r = 1. Also, the variance of a random variable is given the second central moment.
