PROBLEM The rigid bar ABC is supported by a pin at B, vertical steel rod at A and vertical bronze rod at C. Determine the selfweight W of the bar, the vertical movement of the bar at A and C and indicate the direction of movement. For the steel rod, allowable stress equal to 120 MPa and E = 200 GPa. For the bronze rod, allowable stress equal to 60 MPa and E = 83 GPa. Express your answer in N (Newton) for the selfweight of the bar and for the vertical movement answer in 3 decimal places and in mm (millimeter). A = 1200 mm2. A = 300 mm2 1.2 m 0.9 m A B -0.6 m→ 1.2 m

The rigid bar ABC is supported by a pin at B, vertical steel rod at A and vertical bronze rod at C.
Determine the selfweight W of the bar, the vertical movement of the bar at A and C and indicate the
direction of movement. For the steel rod, allowable stress equal to 120 MPa andE = 200 GPa. For
the bronze rod, allowable stress equal to 60 MPa and E = 83 GPa. Express your answer in
N (Newton) for the selfweight of the bar and for the vertical movement answer in 3 decimal places
and in mm (millimeter).
