Matter, Particle and Weight:
Sol: Matter: Matter is anything which occupies space and have some mass, offers resistance to any stress, for example Iron, stone, air, Water.
Particle: A body of negligible dimension is called as particle. But a particle also has mass.
Mass: The properties of matter by which action of one body can be compared with that of another can be defined as mass.
m = ρ.v
Where,
ρ= Density of body
V = Volume of the body as ,
Weight: Weight of body is force with which body is attracted towards center of earth.
Velocity acquired by block - system released from rest: T wo blocks shown in the figure given below, have masses A = 20N and B = 10N and the coefficient of friction between

Equilibrium conditions: What are equilibrium conditions for non concurrent force system? Sol.: For the Equilibrium of non concurrent forces there are three conditions:
INVERTER TYPE POWER SOURCES For site welding and repair applications, a need was felt for long time to have light weight arc welding power source. Even though, a petrol driven ro
FRICTION WELDING In this, friction is employed to generate heat b/w two sliding or rotating metal surfaces. This process is usually carried out by placing the pieces to be welded
