A 50-story building is being planned. It is to be 200.0 high with a base 48.0 by 66.0 . Its total mass will be about 2.5×107 , and its weight therefore about 2.5×108 . Suppose a 200 wind exerts a force of 860 over the 66.0 wide face .
Part A
Calculate the magnitude of the torque about the potential pivot point, the rear edge of the building (where acts in the figure). Assume the total force of the wind acts at the midpoint of the building's face, and that the building is not anchored in bedrock.
