Telling students of your expectations for their behavior on the first day of school does not provide sufficient orientation to the class.

Determine the magnitude of the approximate bending moment at E in girder DE. Let w1 = 20 kN/m, w2 = 40 kN/m, L1 = 10 m, L2 = 5 m, and L3 = 7 m.

Use Robot to determine the magnitude of the vertical reaction force at A. Assume that M = 200 kN·m, P = 70 kN, w = 85 kN/m, and L = 1.6 m. Delete the self-weight of the beam.

Why did the officer initially pat down the suspects?

Use the cantilever method to determine the magnitude of the approximate axial force in column DG. Let P1 = 23.5 kN, P2 = 47.3 kN, L1 = 9 m, and L2 = 6 m.

Using the slope-deflection equations below, determine the beam slope at C. Let P1 = 11 kips, P2 = 13 kips, L1 = 22 ft, L2 = 12 ft, and L3 = 17 ft. Assume EI = constant.MAC = EIθC / 17 + 30.15MCA = EIθC / 8.5 + –55.27MCE = EIθC / 8.5 + 55.25MEC = EIθC / 17 + –55.25

Use Robot to determine the force in member AD. Use a consistent material and cross section for the truss members. Delete the self-weight of the members. Let P = 12 kN, L1 = 6 m, and L2 = 3 m.

Use the cantilever method to determine the magnitude of the approximate axial force in column AD. Let P1 = 14.3 kN, P2 = 33.8 kN, L1 = 8 m, and L2 = 6 m.

Determine the magnitude of the bending moment at B. Let w = 1.1 kip/ft and L = 26 ft. Assume EI = constant.
