Problem 448
A beam carrying the loads shown in Figure P-448 is composed of three segments. It is supported by four vertical reactions and joined by two frictionless hinges. Determine the values of the reactions.
 

Problem 447
The truss are joined as shown in Figure P-447 to form a three-hinged arch. Determine the horizontal and vertical components of the hinge force at B and then determine the type and magnitude of force in bars BD and BE.
 

Problem 446
A three-hinged arch is composed of two trusses hinged together at D in Figure P-446. Compute the components of the reaction at A and find the forces acting in bars AB and AC.
 

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.
