Question:
Evaluating the external loads that the bridge may experience by analyzing a
simplified, D bridge schematic illustrated in Figure The schematic shows a pin support at
Point A and a roller support at Point D The schematic includes a uniform distributed load of
lbin that represents the weight of the bridge made of Aluminum A composite distributed
load located between the pin and roller supports represents the weight of a fullyloaded Ground
Mobility Vehicle GMVsee Figure which has a wheelbase of in Additionally, there
are two suspension cables attached to the bridge deck at Points B and C The cables are also
attached to stanchions posted into the ground on either side of the bridge. Engineers on your
team have initially estimated that the tension in the first cable that is attached at Point B T
needs to be lb They have also determined that the reaction force from the roller support
should not exceed lb Based on this loading condition and the roller support requirement,
you will need to calculate the minimum tension in the second cable T as well as the
resultant magnitude and direction pin reaction at Point A
