For the free-falling patachutist with linear drag, assume a firstjumper is 70 kg and has a drag coefficient of of 12 kg/s. If a second jumper has a dragcoefficient of 15 kg/s and a mass of 75 kg, how long will it take him to reach the same velocity t..
Determine the min coefficient of static friction between tires and the road surface so that the 1.5Mg car does not slide as it travels at 80km/h on the curved road. Neglect the size of the car.
The subsoil at the site is a thick layer of soft alluvial river silts and sands, the bearing capacity of the silt has been found to be in the region of 80 kN/m2. There is a high ground water table present.
thermo-gravimetry of calcium oxalate1. evaluate the percent mass loss for each of the three thermal events indicated
If the resistivity of this alloy is dependent only on thermal and impurity considerations, find the amount of changes in length of the rod (in mm) when the temperature is changed from T1 to 1.47268x10^2 °C.
Select examples of civil engineering works where knowledge of shear strength is required and use these to explain the significance of the drained and undrained tests.
You need to compare measured and predicted deflections for the three situations described below. Comment on reasons for the differences between the predicted and measured values. Recall that E = 69 GN/m2, rho = 2700 kg/m3, and the beam cross-section ..
The footing is supported to carry a net safe load of 400 kN/m^2 with FS = 3. Given Ysat = 20.85 KN/m^3 and phi = 35 degrees, find the required width of the footing using Terzaghi's general shear failure criterion.
