Use Robot to determine the magnitude of the vertical reaction force at A. Let w = 20 kN/m, and L = 9 m. Delete the self-weight of the beam.

Use the portal method to determine the magnitude of the approximate axial force in girder HI. Let P1 = 12.5 kN, P2 = 39.6 kN, L1 = 8 m, L2 = 6 m, and L3 = 6 m.

Use Robot to determine the magnitude of the axial force in column FI. Assume each member is a steel W16x40, but delete the self-weight of the members. Let P1 = 25.0 kN, P2 = 45.0 kN, L1 = 10 m, L2 = 5 m, and L3 = 7 m.

To obtain a simplified determinate structure, internal _______ are inserted in the indeterminate structure at the assumed locations of inflection points.

Use Robot to determine the magnitude of the beam deflection at A for a steel W16x40 beam. Include the self-weight of the beam. Let w = 3.6 kips/ft, P = 50 kips, L1 = 10 ft, and L2 = 15 ft.

Determine the beam slope at B. Let w = 2.7 kip/ft, L1 = 33 ft, and L2 = 21 ft. Assume EI = constant.
