Calculate the range of allowable currents in Problem 31.43 if the temperature should be between 0.7 and 0.8 times the melting temperature of copper. Repeat this problem for carbon steel.
Problem 31.43
Two flat copper sheets (each 1.0 mm thick) are being spot welded by the use of a current of 7000 A and a current flow time of 0.3 s. The electrodes are 4 mm in diameter. Estimate the heat generated in the weld zone. Assume that the resistance is 200 μ Ω .
An embankment for a highway 30 m wide and 1.5 m in compacted thickness is to be constructed from a sandy soil trucked from a borrow pit. The water content, w
A survey of similar facilities indicates that one parking space must be provided for every one employee and that 60% of all automobiles driven to work are compact automobiles, six percent of the spaces should be allocated for the handicapped.
Distance between concrete columns in 5 story building and if there is distance 15 feet than what should be the column size and how many bars and diameter of each bar?
A rectangular culvert 4 feet x 6 feet is running full and discharging 3,500 cfm. There is no friction loss. Find the velocity in fps. The culvert empties into a 10 ft wide culvert and the velocity reduces to 0.6 fps. How deep is the water level in th..
a piston/cylinder contains liquid water at 2 degrees Celcius, with a freely moving piston maintains a pressure of 200 kPa on the water. Heat transfers to the liquid water until the piston/cylinder contains only saturated vapor.
Place the scientific mass on the inclined plane and string over the pulley. Using a force-measuring device, pull the string and determine the force needed to obtain static equilibrium.
The testing machin that covers the right range of load is to be chosen. it is expected to load the material up to a strains of 3%. if th material must remain elastic over that range, what would be the maximum load
Is it possible to cause yielding of the entire Ni layer before reaching the room temperature?
A constant flow of water, 30 lbm/s, enters a cylindrical container from the top. At the bottom, an opening allows water to drain out at a rate, in lbm/s, that is proportional to H(t), the instantaneous height of water in the barrel, in ft
Water with a static pressure of 1.96kN/M2 flows through an 800 mm diameter pipe. A pitot tube pressure gage in this pipe reads a pressure of 5.88 kN/M2. Determine the velocity (V)
Tension in the spring connecting the two arms of the lifting tongs is 150 lb.
