WebbIn either case we can use vector notation and suppose that r1, r2, r3 are the position vectors of m 1, m2, m3 with respect to the origin, and the centre of mass is a point whose position vector r is defined by . M ∑mi i = r r 1.1.3 In this case the sum is a vector sum and ∑mi ir, a vector quantity, is the first moment of mass with respect ... Webb14 juli 2024 · Pick a tiny step size. Let’s say I have tiny blocks with size of 0.01 by 0.01. Find the vector location of this block and its mass (all blocks have the same mass). Use the sum formula version of the center of mass. Move the block along until all parts of the triangle are covered. Let’s do this. OK, there is a small difficulty.
