The two uniform 4.6 - kg bars DC and EF are fixed (welded) together at E. At the instant 8 = 60BC has 4ra-2 an angular velocity w= 2ra and an angular acceleration = Part A Determine the magnitude of the normal force N which DC exerts on EF at E. Express your answer to three significant figures and include the appropriate units. Part B Determine the magnitude of the shear force Vwhich DC exerts on EF at E. Express your answer to three significant figures and include the appropriate units. Part C Determine the magnitude of the moment M, which DC exerts on EF at E. Express your answer to three significant figures and include the appropriate units.
