A 50-story building is being planned. It is to be 180.0 m high with a base 46.0 m by 76.0 m. Its total mass will be about 1.8 x 107 kg, and its weight therefore about 1.8 x 10° N. Suppose a 200-km/h wind exerts a force of 950 N/m² over the 76.0-m-wide face (Fig. 9–80). Calculate the torque about the potential pivot point, the rear edge_ of the building (where Fp acts in Fig. 9–80), and determine whether the building will topple. Assume the total force of the wind acts at I口 the midpoint of the build- ing's face, and that the building is not anchored in bedrock. [Hint: Fe in Fig. 9-80 represents the force that the Earth would ... mg exert on the building in the case where the building would just begin to tip.] FIGURE 9-80 Forces on a building subjected to wind (FA), gravity (mg), and the force FE on the building due to the Earth if the building were just about to tip. Problem 61.

Dont use AI A tall, cylindrical chimney falls over when its base is ruptured. Treat the chimney as a thin rod of length 53.2 m. At the instant it makes an angle of 34.1° with the vertical as it falls, what are (a) the radial acceleration of the top, and (b) the tangential acceleration of the top. (Hint: Use energy considerations, not a torque.) (c) At what angle θ is the tangential acceleration equal to g? Assume free-fall acceleration to be equal to 9.81 m/s2.
