In a slider crank mechanism the length of the crank OB is (100+X)mm and length of the connecting rod is (475+X)mm. The center of gravity G of the connecting rod is (250+X)mm from the slider A. crank speed is (500+X)rpm clockwise. When the crank has turned 45 deg. From the inner dead center. Determine( using both relative velocity method and Instantaneous center method) 1. Velocity of the slider 2. Velocity of point G 3. Angular velocity of the connecting rod AB Note where X is two digit number made from the last two digit of the registration number of the students For example if the reg. no. of the student is 11912081 then X=81 Draw the neat and clean diagram with proper scale. Rough drawings will not be considered
In crank and slotted lever quick return mechanism, the crank length is (100 +X )mm and the distance between the fixed center is (225+X)mm. The length of the slotted lever is (525+X)mm. Determine the ration of time of cutting stroke to time of return stroke. Also calculate the length of the stroke . Note where X is two digit number made from the last two digit of the registration number of the students For example if the reg. no. of the student is 11912081 then X=81 and crank length is 80+81=161mm Draw the neat and clean diagram with proper scale. Rough drawings will not be considered.
