The van seen from the rear is traveling at a speed v around a turn of mean radius r banked inward at an angle θ. The effective coefficient of friction between the tires and the road is μ Determine (a) the proper bank angle for a given v to eliminate any tendency to slip or tip, and (b) the maximum speed v before the van tips or slips for a given . Note that the forces and the acceleration lie in the plane of the figure so that the problem may be treated as one of plane motion even though the velocity is normal to this plane.
The heat resisting alloy S-590 is used for a component that will be exposed to 700°C. With a safety factor of two on the time, determine the maximum static stress the component must sustain in order to have a service life of 10000 hours.
An 1100 ft. straight line route survey, which had PI's at3+81.27 (I = 12o30') and 5+42.30 (I = 10o56'), laterhad 600 ft radius simple curves inserted at each PI. Computethe following: a)Curve data for each curve: Da, T, L, LC, E, and MO
A bridge having a horizontal top cord is span between tow piers Aand B having an arbitrary height. It is required that apin-connected truss be used, consisting of steel members boltedtogether to steel gusset plates. The end supports are assumed to be..
A man riding upward in a freight elevator drops a package off the elevator when it is 100 ft. from the ground. Part A: if the elevator maintains a constant upward speed of 4 ft/s,
determine the mass of each of the two cylinders if they cause sag of s=0.5 when suspended from the rings a A and B.Note that s=0 when the cylinders are removed
Also calculate the deflection of the beam to check that it complies with the design limit of L/200. Only variable actions are required for deflection check.
Vision Technologies Inc., is a small company that uses ultra-wideband technology to develop devices that can detect objects (including people) inside of buildings, behind walls, or below ground.
Derive the expressions for the concentration exiting a CSTR and a PFR for a zero order removal reaction. Which reactor design is more efficient in terms of volume and hydraulic retention times?
The company Eco-Safe is adding pollution control equipment to its process and reducing emission of pollutants. The annual waste disposal cost of the current process is $130,000 and the annual operating cost is $600,000
A spherical pressure vessel has an outer diameter of 10 ft and a wall thickness of 0.5 in. knowing that for the steel used ?all= 12 ski, E= 29 x 10^6 psi, and v= 0.29, determine (a) the allowable gage pressure, (b) the corresponding increase in the d..
A power plant operates at steady-state. It receives energy from a hot source (combustion of fuel) at a temperature of 420 oC. The plant discharges this energy to a nearby river that acts as a cold source.
