Question

This is a standard truck used for bridge design. Use the top values for the HS20-44 truck

All problems refer to a 40' long simply supported beam subjected to the following load group.
V = 14'

Draw an influence line for the moment at the center of the beam. Determine the maximum moment at the center of the beam. Provide the answer in kip-ft.
Draw an influence line for the shear at the center of the beam. Determine the maximum shear at the center of the beam. Provide the answer in kips (absolute value).
Determine the maximum absolute shear anywhere on the beam, for a load also located anywhere. Provide the answer in kips.
