Hello everyone , today i am going to solve some numericals on Klein's Construction. Previously i have explained you how to apply this method on single slider crank mechanism. If you are first time here then i insist you to view the first part on this topic here :  farooq blogs kleins construction In first numerical there is center of gravity of connecting rod given and we have to calculate the angular acceleration of CG of connecting rod. In second numerical the crank length and connecting rod are given in the form of stroke and obliquity ratio , first we have to calculate length of crank and connecting rod . Ques 1 . Determine the velocity and acceleration of each link in a single slider crank mechanism by using Klein's Construction method .Also determine the acceleration of center of gravity of connecting rod. Crank length= 90 mm Connecting Rod length= 450 mm Crank angle from IDC= 30 deg. Center of gravity of connecting rod from crankpin= 180 mm Speed N=600 rp...

Klein's Construction - is an graphical method to find velocity and acceleration of reciprocating parts of steam engine or internal combustion engine . In Klein's Construction the velocity and acceleration diagrams are made on configuration diagram itself. The line that represents the crank in the configuration diagram also represents the velocity and acceleration of its moving end in the velocity and acceleration diagrams respectively. By using this method we can find the velocity and acceleration of crank,connecting rod ,piston. Klein's Construction This method is applicable only if α of crank=0 or ω of crank=constant Method of obtaining velocity and acceleration  from the given values of crank length(r) and its angular velocity(ω) calculate crank velocity by  crank velocity Vc=r*ω crank acceleration Ac=r*ω*ω if dimensions of crank and connecting rod are such that they can be drawn on paper then there is no need to scale down the dimenions. if ...
