• The polygon law of forces states that if a number of forces, acting simultaneously on a particle, be represented in magnitude and direction by the sides a polygon taken in order, then their resultant is represented in magnitude and direction by the closing side of the polygon, taken in opposite direction.
• The triangle law of forces states that if two forces acting simultaneously on a particle, be represented in magnitude and direction by the two sides of a triangle taken in order, then their resultant may be represented in mangnitude and direction by the third side of of a triangle, taken in opposite order.
• Two like parallel forces are acting at a distance of 24 mm apart and their resultant is 20 N. If the line of action of the resultant is 6 mm from any given force the two forces are
• If the resultant of two equal forces has the same magnitude as either of the forces, then angle between the two forces is
• The algebraic sum of the resolved parts of a number of forces in a given direction is equal to the resolved part of their resultant in the same direction. This is known as
• Three forces acting on a rigid body are represented in magnitude, direction and line of action by the three sides of a triangle taken in order. The forces are equivalent to a couple whose moment is equal to
• A resultant force is a single force which produces the same effect as produced by all the given forces acting on a body
• The resultant of the two forces P and Q is R. If Q is doubled, the new resultant is perpendicular to P. Then
• If a number of forces are acting at a point, their resultant will be inclined at an angle ? with the horizontal, such that
• Two forces are acting at an angle of 120?. The bigger force is 40N and the resultant is perpendicular to the smaller one. The smaller force is
