The Mechanicals

Important points of Engineering Mechanics Force = Newton 1 kgf = 9.8 N Process of finding force = Co position Vector method =  Polygon law force Resultant force = sq.root (2P) sigma H = Equilibrium Sigma R = Not Equilibrium Mass Moment of Inertia = kg-m2 Movement of inertia = m4 Important points of Engineering Mechanics Moment of inertia rectangle to width = (1/12)bd3 Moment of inertia rectangle to depth = (1/12)db3 Moment of inertia sphere = (a4)/12 Moment of inertia of circle about diameter = (pi/64)d4 Moment of inertia of circle about axis = (pi/32)d4 Moment of inertia triangle about base = (bh3)/36 Moment of inertia triangle about axis = (bh3)/12 Moment of inertia solid sphere = (2mr2)/5 Ideal machine efficiency = 100% Non reversible machine =  self locking Reversible machine <50% Non reversible machine >50% Screw jack is non reversible machine Low power machine (P) = mW +  c , P=effort , W= Load Maximum advantage lifting mach...

Engineering Mechanics                                                              Branch of engineering science which deals with principle of mechanics and application of engineering problems There 2 types of Mechanics 1. Static mechanics : it Deals with force and there effect which deals at rest. 2. Dynamic mechanics :  it Deals with force and there effect which deals at motion.          in dynamic there are 2 types  Kinetics :  it Deals with force and there effect which deals at motion due to application of force Kinematics :  it Deals with force and there effect which deals at motion without taking in account force which responsible for motion.  Force : it produce or tends to produce , destroy of tends to destroy the motion of body, which acting on bod...
