150 mm A /60° 60 B -R Prob. 4-67

The ABC rigid bar is suspended by the BD rigid bar and by an A pin that connects it to the other ADE rigid bar. If the overhang load at point C is equal to 12kN, calculate the force on the BD bar and the reactions FA = √??2 + ??2, on pin A and the reaction FE roller located at point E. Disregard the weights of all the bars.

(5) Determine the components of reaction at the pin A and rocker B. Hint: The support at C is a peg in the slot in member DC, and allows translation along but prevents it in the direction perpendular to member DC.

Part E The shaft is supported at its ends by two bearings A and B and is subjected to the forces applied to the pulleys fixed to the shaft. (Figure 1) The T = 585-N forces act in the -z direction and the 200-N and 80-N forces act in the +y direction. The journal bearings at A and B exert only y and z components of force on the shaft. Determine the resultant bending moment in the y direction on the cross section at C. Express your answer to three significant figures and include appropriate units.
