Compute the horizontal and vertical components of force at pin B. The belt is subjected to a tension of T=100 N and passes over each of the three pulleys. 

B_{x} = 0 N, B_{y} = 141.4 N  
B_{x} = 15.89 N, B_{y} = 120.7 N  
B_{x} = 0, B_{y} = 100.0 N  
B_{x} = 20.7 N, B_{y} = 157.3 N  

Determine the horizontal and vertical components of reaction at the pin A and the reaction at the roller support B required for equilibrium of the truss. 

A_{x} = 154.0 lb, A_{y} = 333 lb, N_{B} = 308 lb  
A_{x} = 267 lb, A_{y} = 223 lb, N_{B} = 377 lb  
A_{x} = 0, A_{y} = 333 lb, N_{B} = 267 lb  
A_{x} = 462 lb, A_{y} = 66.7 lb, N_{B} = 533 lb  

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.
