The phenomenon of vehicle tripping is investigated here. The sport-utility vehicle is sliding sideways with speed v1 and no angular velocity when it strikes a small curb. Assume no rebound of the right-side tires and estimate the minimum speed v1 which will cause the vehicle to roll completely over to its right side.
The mass of the SUV is 2300 kg and its mass moment of inertia about a longitudinal axis through the mass center G is 900 kg.m2.
Nitrogen flows through a converging-diverging nozzle designed to operate at a Mach number of 3.0. It it is subjected to an operating pressure ratio of 0.5: Determine the Mach number at the exit.
Find the reactions and draw complete shear and moment diagrams.- Assume that the center support settles 0.3 in. Find the reactions and draw complete shear and moment diagrams.
Determine the displacement and stress fields in the spherical body. Using the stress field obtained, determine the stresses at the surface of a rigid inclusion in an infinite elastic medium.
Ten kilograms of water at 15° C and 700 kPa are contained in a cylinder as shown. Heat is transferred slowly causing the piston to rise. Determine the heat transfer and work done if the final condition is saturated vapor. Show the process on a T-v di..
Water flows in the symmetrical, unfinished concrete trapezoidal channel shown in Fig. P10.77 at a rate of 120 ft3 /s. The slope is 4.2 ft/2000 ft. Determine the number of cubic yards of concrete needed to line each 1000 ft of the channel.
a 1kg fluid is compressed reversibly according to a law pv0.25 where p is in bar and v is in m3kg. the final volume is
Calculate the number of vacancies per cubic meter in some metal at 753°C. The energy for vacancy formation is 0.81 eV/atom, while the density and atomic weight for this metal are 6.38 g/cm3 and 49.43 g/mol, respectively. Find in m^-3 units.
