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.

A smooth cylinder lying on a __________ is in neutral equilibrium.
-
The velocity of a particle (v) moving with simple harmonic motion, at any instant is given by(where r = Amplitude of motion, and y = Displacement of the particle from mean position.)
-
Varingon's theorem of moments states that if a number of coplaner forces acting on a particle are in equilibrium, then

A block ot mass 20 kg lying on a rough horizontal plane is connected by a light string passing over a smooth pulley to another mass 5 kg, which can move freely in the Vertical direction, as shown in the below figure. The tension in the string will __________ with the increase in coefficient of friction.
