Question

a) P16-2. The crank AB turns counterclockwise at a constant rate o causing the connecting arm CD and rocking beam DE to move. Draw a sketch showing the location of the IC for the connecting arm when 0 = 0°, 90°, 180°, and 270°. Also, how was the curvature of the head at E determined, and why is it curved in this way?

Answer 1

* Sol: AB=W Angular Velocity of crank When 0=0° Ic u center-6 Radius of gh fas Curvature PELS WR angreich q4- w IL, " 4-<-- Vou to the lathen 0 - 900 No of task = 4 Ic Center =6 Radius of curredhen was be found 11awa WI - Kto u Ris & ho - 1

Wen 0 = 180° A. Ic.6 of curvature Radius be can Rtu When O= 270° No. of IC=6 Rodius of curratuse of Cronk DE con be found by equation
