what u r telling is correct from design point of view,but my sir told this problem to solve it.i wil go and ask him what exactly did he see, thanks

thanks for the address provided,in that 2.keyed shaft diagram,the effective key height reduces (h)as i told earlier the key hits the keyway of shaft ,thereby increasing the width at the edges(the contact area of key to shaft reduces),thus decreasing the torque transmitted by the key. i know the...

sorry,i can't upload the figure, imagine a key resting on the key way of shaft,then due to sudden forward & reversig the key makes the keyway(of shaft) larger,thus decreasing the area of contact of key to the shaft along the rectangular perimeter, i need a analysis software to find at what...

i have to find out why the key in output pulley fails due to sudden forward and reversing(in gearbox of lathe)i did some theoretical calculations in crushing & shear stress.please tel some solution regarding analysis of the key
