Applied Mechanics
22.
According to Law of Triangle of Forces
three forces acting at a point, can be rep-resented by the sides of a triangle, each side being in proportion to the force
three forces acting along the sides of a triangle are always in equilibrium
if three forces acting on a, point can be represented.in magnitude and direction, by the sides of a triangle taken in order, these 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
if the forces acting on a particle be represented in magnitude and direction by the two sides of a triangle taken in order, their resultant will be represented in magnitude and direction by the third side of the triangle, taken in opposite order.
