Strength of Materials
The resultant of the following three couples 20 kg force, 0.5 m arm, + ve sense 30 kg force, 1 m arm, – ve sense 40 kg force, 0.25 m arm, + ve sense having arm of 0.5 m will be
If three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two
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
Three forces acting at a point can be represented by a triangle, each side being proportional to force
