Lesson Worksheet: Moment of a Force about a Point in 2D: Scalar Mathematics
In this worksheet, we will practice finding the sum of moments of a group of forces acting on a body about a point in 2D.
In the figure, determine the magnitude of the sum of the moments of the forces 13 N, 18 N, and 7 N about rounding your answer to two decimal places.
Determine the moment of the force that has a magnitude of 11 N about point . Give your answer in N⋅m.
In the given figure, find the magnitude of the sum of the moments about of the forces whose magnitudes are 5 N and 18 N.
is an isosceles triangle in which and . Forces of 20, 17, and newtons are acting on , , and , respectively. Find the sum of the moments of the forces about the midpoint of , given that the positive direction is .
is an equilateral triangle, having a side length of 4 cm. Knowing that forces of magnitudes 150 N, 400 N, and 50 N are acting as shown in the figure, determine the sum of the moments of these forces about the point of intersection of the triangle’s medians, rounded to two decimal places.
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 .
