Question

6. The assembly shown rotates about the rod AC. At the instant shown, the assembly has an angular velocity of 5 rad/s that is increasing with an angular acceleration of 25 rad/s2. Knowing that the y-component of the velocity of corner D is negative at this instant in time, determine the velocity and acceleration of corner E. Y B с 200 mm 130 mm 100 mm D E 240 mm

Answer 1

sol - given data Assembly angular relocity = 5 rad) sec Angular acceferation ob as radla² Determine Velocity & acceleration of point E= =? Velocity at E = -wxr lave sign because of directon of velocity! of r 200 E= -wyr 100 w=5; ra 2 200 2 t1oo Foooo

wwgi866 V- -wyr - -51223.6 -1118 mala relocity at at E = - 1118 mola Acceleration 2x8 2=25 25X 223.6 = 5590 mm 118² :. Acceler ation at E 8lwwebss
