Statics sum of moments
WebSum of moments The diagram shows a set of forces acting on a light rod. Calculate the sum of the moments about the point P P. Solution Each force is already perpendicular to the point P P. The moment of the 6N 6 N force is 6 ×2 = 12Nm 6 × 2 = 12 N m anticlockwise. The moment of the 14N 14 N force is 14×2 =28Nm 14 × 2 = 28 N m clockwise. http://mechanicsmap.psu.edu/websites/3_equilibrium_rigid_body/3-6_equilibrium_equations_rigid_body/equilibrium_equations_rigid_body.html

Did you know?
In addition to the tendency to move a body in the direction of its application, a force can also tend to rotate a body about an axis. The axis may be any line which neither intersects nor is parallel to the line of action of the force. This rotational tendency is known as the moment (M) of the force. Moment is also referred to as torque.

WebSum up the forces in the horizontal direction. In a simply supported beam, the only horizontal force is the 5kN/m force, which when multiplied by the length of the member (L = 10) we get 5*10 = 50 kN. Write an equation for the horizontal forces: ∑Fy = 0 = RA + RB - wL = RA + RB - 5*10 RA + RB = 50 kN
