Solve previous. Problem 22.17 except that the work-piece is 5.0 in wide and the cutter is offset to one side so that the swath cut by the cutter = 1.0 in wide.
Problem 22.17
A face milling operation is performed to finish the top surface of a steel rectangular work piece 12.0 in long x 2.0 in wide. The milling cutter has four teeth (cemented carbide inserts) and a 3,0 in diameter. Cutting conditions are: cutting speed = 500 ft/min, feed = 0.010 in/tooth, and depth of cut = 0.150 in. Determine
(a) the time to make one pass across the surface and
(b) the maximum metal removal rate during the cut.
Engineers propose putting flashboards on the dam to raise the water level to 10 ft. Residents a half mile upstream are worried about flooding above their present water depth of about 2.2 ft. Using Eq. (10.52) in one big half-mile step, estimate th..
A rectangular channel carries discharge of 10 m^2/s per unit width, with a sluice gate. Calculate the flow depth y3, if a hydraulic jump forms downstream of the sluice gate when y1 = 20 m.
A concrete sewer pipe 1m in diameter is laid so it has a drop in elevation of 30cm per 300m of length. If sewage (assume the properties are the same as those of water) flows at a depth of 50cm in the pipe,
Suppose the annual traffic flow in one of these one-way streets is 100,000 vehicles and 5% of them would encounter the amber signal light. Estimate the number of accidents per year in the intersection that would be traced back to vehicles running thr..
The position of a particle is given by r =3.0tf +2.0t2]+ 5.0k , where t is in seconds and the coefficients have the proper units for r( t) to be in meters.
A rectangle channel 20 feet wide carries a discharge Q= 200cfs. Compute the critical depth and critical velocity for the flow in the channel.
At what depth would the vertical effective stress in a deep deposit of clay be 100 kpa, if e=1.1? The ground water level is a 1 m delow ground surface and S=95% above the groundwater level. Neglect pore air pressure.
Determine the displacements as a function of time over the interval 0 =t = 10 sec and specify its value at the indicated times.
List all the materials that you see, including different surface treatments and textures - Address all the transparent surfaces that might appear, how will model or show what is beyond those windows?
A certain gas weighs 16.0 N/m3 at a certain temperature and pressure. What are the values of its density, specific volume, and specific gravity relative to air weighing 12.0 N/m3 ?
determine the temperature of propane when the pressure in the tank drops to 1 atm. Also determine the total amount of heat transfer from the environment to the tank to vaporize the entire propane in the tank.
A speedboat on hydrofoils is moving at 20 m/s in a freshwater lake. Each hydrofoil is 3 m below the surface. Assuming, as an apporximation, frictionless, incompressible flow, find the stagnation pressure(gage) at the front of each hydrofoil.
