Discussion :: Equilibrium of a Rigid Body - General Questions (Q.No.13)


The oil rig is supported on the trailer by the pin or axle at A and the frame at B. If the rig has a weight of 115,000 lb and the center of gravity at G, determine the force F that must de developed along the hydraulic cylinder CD in order to start lifting the rig (slowly) off B toward the vertical. Also compute the horizontal and vertical components of reaction at the pin A.

[A]. Ax = 343 kip, Ay = -172.5 kip, FCD = 447 kip
[B]. Ax = 205 kip, Ay = -57.5 kip, FCD = 268 kip
[C]. Ax = 241 kip, Ay = -172.5 kip, FCD = 375 kip
[D]. Ax = 220 kip, Ay = -70.1 kip, FCD = 288 kip

Answer: Option A

I'm having troubles finding FCD. How do you go about this?

Please explain me.
