total mass
[total mass|total mass] is the expression in the denominator, m, +m, representing the sum of individual masses in a system.
Definition
total mass is the expression in the denominator, m, +m, representing the sum of individual masses in a system.
Mechanism
total mass To calculate the total mass, sum the individual masses: m = 2 + 6 + 4 = 12 kg. Next, determine moments with respect to the x- and y-axes: Mx = -2 + 64 + 8 = 12, My = 6 + 6 - 8 = 4. The center of mass is derived from these values.
Effects
total mass affects the moment of the system. The total mass is calculated by multiplying the area of the rectangle by p, then applying the given formula pf(x* )Ax.
