Problem 445
The frame shown in Figure P-445 is supported by a hinge at E and a roller at D. Compute the horizontal and vertical components of the hinge force at C as it acts upon BD.
 

Problem 444
The frame shown in Figure P-444 is supported by a hinge at A and a roller at E. Compute the horizontal and vertical components of the hinge forces at B and C as they act upon member AC.
 

Problem 443
The frame shown in Figure P-443 is hinged to rigid supports at A and E. Find the components of the hinge forces A and E and the forces in members BC and BD.
 

Problem 442
Each member of the frame shown in Figure P-348 weighs 50 lb per ft. Compute the horizontal and vertical components of the pin pressure at C, D, and F.
 

Problem 441
the structure shown in Figure P-441 is hinged at A and C. Find the horizontal and vertical components of the hinge force at B, C, and A.
 

Problem 440
For the frame loaded as shown in Figure P-440, determine the horizontal and vertical components of the pin pressure at B. Specify directions (up or down; left or right) of the force as it acts upon member CD.
 

Problem 438
The center diagonals of the truss in Figure P-438 can support tension only. Compute the force in each center diagonal and the force in BC, DE, and FG.
 

Problem 437
The center panel of the truss in Figure P-437 contains two flexible cables. What load P will cause a compressive force of 20 kN in BD? Then determine which tension diagonal BE or CD is acting and the force in it.
 

In Figure P-420, assume that counter diagonals act from B to E and from E to F in addition to the counter diagonals CD and DG shown in the figure. Assuming that these counter diagonals can support tension only, determine which diagonals are acting and the force in each.
 

Problem 435
For the transmission tower shown in Fig. P-435, determine the force in member CJ.
