Find the centre of mass of the 2D shape bounded by the lines y = ±1.3x between x = 0 to 2.1. Assume the density is uniform with the value: 3.5kg. m-2 Also find the centre of mass of the 3D volume created by rotating the same lines about the x-axis. The density is uniform with the value: 1.9kg. m (Give all your answers rounded to 3 significant figures.) a) Enter the mass (kg) of the 2D plate: Enter the Moment (kg.m) of the 2D plate about the y-axis: Enter the x-coordinate (m) of the centre of mass of the 2D plate: S Enter the mass (kg) of the 3D body: Enter the Moment (kg.m) of the 3D body about the y-axis: Enter the x-coordinate (m) of the centre of mass of the 3D body: a ed db) ks 10
