## Applied Mechanics and Graphic Statics Parallelogram Law of Forces states, "if two forces acting simultaneously on a particle be represented in magnitude and direction by two adjacent sides of a parallelogram, their resultant may be represented in magnitude and direction by

Its longer side
Its shorter side
The diagonal of the parallelogram which does not pass through the point of intersection of the forces
The diagonal of the parallelogram which passes through the point of intersection of the forces

## Applied Mechanics and Graphic Statics A body is said to move with Simple Harmonic Motion if its acceleration, is

Proportional to the square of the distance from the point of reference
Proportional to the distance from the point of reference and directed towards it
Always directed away from the centre, the point of reference
Inversely proportion to the distance from the point of reference

## Applied Mechanics and Graphic Statics The resultant of two forces ‘P’ and ‘Q’ acting at an angle ‘θ’, is

P² + Q² + 2PQ cos θ
√(P² + Q² + 2PQ cos θ)
P² + Q² + 2P sin θ
P² + Q² + 2PQ tan θ
