task
Need help please. A 2 m high, 4 m wide rectangular advertisement panel is attached to a 4 m wide, 0.15 m high rectangular concrete block (density = 2300 kg/m3 ) by two 5 cm diameter 4 m high poles as shown in Figure 2. If the sign is to withstand 150 km/h winds, determine (a) the maximum drag force on the panel, (b) the drag force acting on the poles, and (c) the minimum length L, of the concrete block for the panels to resist the winds.

EXAMPLE 4.1 Consider a concrete beam of rectangular section, 150 mm wide by 300 mm deep, prestressed by 4 high-tensile wires of 5 mm diameter stressed to 1200 N/mmº. The wires are located at an eccentricity of 50 mm. The stresses developed at the soffit of the beam will be examined by considering the nominal concrete and 'equivalent concrete section. Prestressing force = (1200 x 80) = 96,000 N. For the nominal concrete section, A = 45,000...

The drag coefficient of a car at the design conditions of 1 atm, 25°C, and 90 km/h is to be determined experimentally in a large wind tunnel in a full-scale test. The height and width of the car are 1.25 m and 1.65 m, respectively. If the horizontal force acting on the car is measured to be 300 N, determine the total drag coefficient of this car. Take the density of air at 1 atm and 25°C as p 1164...
