A Four bar chain ABCD has a fixed link AD = 700mm, the driving crank AB= 200mm, the driven crank CD = 400mm and the connecting link BC=900mm. Find the velocity and acceleration of Point ‘P’ midway between B and C when the angle BAD = 600 and AB rotates anticlockwise at a uniform speed of 600 rpm.
Gives
AB=200mm
CD=400mm
BC=900mm
Angle ( BAD)=60°
Speed "(w)=2\\pi n"
"w=\\frac{2\\pi \\times600}{60}=20\\pi" rad/sec
r=AB=0.2m
"a_c=\\frac{v^2}{r}=\\frac{12.56^2}{0.2}=788.768m\/sec^2"
