Suppose a car's standard tires are replaced with tires 1.20 times larger in diameter. Complete the following sentences. (i) The car's speedometer reading will be 1.44 times too high. 1.20 times too high. accurate. 1.20 times too low. 1.44 times too low. inaccurate by an unpredictable factor. Incorrect: Your answer is incorrect. (ii) The car's fuel economy in miles per gallon or km/L will appear to be

In a wind tunnel the speed changes as the cross sectional area of the tunnel changes. if the speed in a 6' x 6' square test section is 100 mph, what was the speed upstream of the test section where the tunnel measured 20' x 20'? use conservation of mass and assume incompressible flow. conservation of mass requires that as the flow moves through a path or a duct the product of the density, velocity and cross sectional area must remain constant; i.e., that ova-constant. a model is being tested in a wind tunnel at a speed of 100 mph if the flow in the test section is at sea level standard conditions, what is the pressure at the model's stagnation point? (a) the tunnel speed is being measured by a pitot-static tube connected to a u- tube manometer. what is the reading on that manometer in inches of water? (b) at one point on the model a pressure of 2058 psf is measured. what is the local airspeed at that point?

The a992 steel rod bc has a diameter of 50 mm and is used as a strut to support the beam. determine the maximum intensity w of the uniform distributed load that can be applied to the beam without risk of causing the strut to buckle. take f.s. = 2 against bucklin

Holes drilled several kilometers into earth’s crust provide direct evidence about earth’s interior in the form of
