wall crane supports

1. The structure below is supported by a pin at A and a roller at B. Determine the pin reactions at E, C, and D. 4 F 3'-0" 5000 lb 6'-0" B 2'-0" CH D 8'-0" 6'-0"

For the frame shown, assume that A, B, and C are pin connections. The purlin loads such as D and E are applied perpendicular to the center line of each girder. Determine the horizontal and vertical reactions at the connections A and C of the gable frame. Draw the shear diagram for sloping members and columns. 20 kN 20 kN 40 kN 40 kN EF 30 kN 30 kN G 2.5 m 20 kN kN/m 5 m 3 m 3 m 3 m 3 m- Answer with text and/or attachments:

5. The tension in cable BC is 100 lbs. Determine the reactions at the fixed support. Note that the L-shaped bar has an applied load of 200 lbs and an applied couple of 300 ft-lbs. B 200 lb -3 3 ft-3 ft- -6 ft- C 6 ft 300 ft-lb
