Q3. Beam OA is supported by a ball and socket joint at O and Cables AB and AC. If a 150 N force is applied at the mid-point of the beam, determine the magnitudes of the tension forces in both cables and the reaction components at the ball and socket support. X A. 2 m B 1 m) 2 m Z 2 m 3 m C 3 m

The bar is snugly fit between points C and A before the loading is applied at Collar B. Assume E = 200 GPa for the steel. The circular bars in the assembly are solid. The bars are solid with a diameter of 15 mm. Assume a fixed rigid support at C and A. A C В 6 kN 3 m 2 m A) Show the FBD and compatibility equation for this problem. B) Determine the support reactions at A and C. (Horizontal forces only) Left side: Fc = Right side: FA =

2. The scoop holds a 2,000 N weight concentrated at G. If all links are in duplicate, determine the vertical reaction at joint K (Fxy). Note that HL is connected to the truck body and LKJ is a single member. -320 mm 260 mm B 180 mm 100 mm D 160 mm K 1040 mm 380 mm |200 mm 1120 mm Answer: FKy = 403.3613 N ↑
