Question: a uniform rigid bar is supported by a ball and...

Question details

A uniform rigid bar is supported by a ball and a socket support at point O and two cables AC and BD attached to the wall. Mass of the rigid bar is 80 kg and its weight W is acting at the center of the rigid bar 1.8 mi (a) Draw the free body diagram of the rigid bar by 1 2 m showing its weight and the forces in cables AC and BD, and all reaction forces at point O. 3 m 1 (b) Determine the position vectors of point A, B, C, (c) Determine the unit vectors along AC and BD. forces carried by cables AC and BD, and the 1 m1.5m and D. (d) Using equilibrium equations, determine the reaction forces at point O CTake the gravitational acceleration g-10m/s)
