Strength of Materials
The M.I. of hollow circular section about a central axis perpendicular to section as compared to its M.I. about horizontal axis is
If three forces acting upon a particle are represented in magnitude and direction by the sides of a triangle, taken in order, they will be in equilibrium
Three forces acting at a point will be in equilibrium
If three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two
Three forces acting at a point can be represented by a triangle, each side being proportional to force
