is a rhombus having a side length 2 cm in which . Forces of magnitudes 2 N, 6 N, 2 N, N, and 4 N are acting along , , , , and , respectively. If the sum of the moments of these forces about equals the sum of moments of the forces about the point of intersection of the two diagonals of the rhombus, find .
is a rectangle, where and , and forces of magnitudes 24, 30, 8, and 30 newtons are acting along , , , and , respectively. If the point , where the sum of the moments of the forces about is 53 N⋅cm in the direction of , determine the length of .
is a rectangle, where is the midpoint of , , and . Forces of magnitudes 10, 20, and 12 newtons are acting along , , and , respectively, and a force of magnitude N is acting at the point . If the algebraic sum of the moments of the forces about is 160 N⋅cm, determine the angle between the force of magnitude N and .
