Problem 1) In mechanism shown below, the crank OA is 100 mm long and rotates in a clockwise direction at a speed of 200 rpm. The straight rod BCD rocks on a fixed point at C. The links BC and CD are each 200 mm long and the link AB is 300 mm long. The slider E, which is driven by the rod DE is 250 mm long. Find the velocity of slider E at shown instant: 1. Using vectors graphical method. 2. Using Instant center method. 3. Using Vector loop method (Excel sheet. Hint: 4 bar linkage then slider crank)
