Program Appears Frozen The human resources department has just released a new program used to calculate payroll for each employee. After you enter the payroll data for each employee, you click a button to calculate everyone's pay for that pay period. After clicking the button, the program becomes unresponsive and appears frozen. What might be wrong?
A spherical water droplet having a diameter of 1.3 mm is allowed to fall from rest in atmospheric air at 1 atm and 20C. Estimate the velocities the duplet will attain after a drop of 30, 60, and 300 m.
Estimate the fuel savings for one year on a semitruck that travels 300 000 mi if fuel costs $2.50/gal if the truck installs both a de?ector and a gap seal. Without the de?ector and seal the truck averages 4 mi/gal. If an owner desires a three-year..
determine a the velocity and acceleration of point p on the rim of the wheel when t0.5 s and b the total distance the
Figure P15.23 shows a two-stage gear reducer. Identical pairs of gears are used. (This enables input shaft a and output shaft c to be colinear, which facilitates machining of the housing.) Shaft b, called the countershaft, turns freely in bearings..
One good practice is approaching a manufacturing company and focusing on one of the older machineries and/or products - Another approach is choosing a simple product like a paper clip, buy/ make a number of them... and conduct test/analysis on that ..
The welded handle and stand on the tank weigh 1 lbs (combined) and valve on the tank weighs 1.5 lbs and has an exit area of 1 cm^2 . What is the wall thickness of the propane tank in mm? what is the inner volume of the propane tank in mL and gallons..
the velocity of a lift increases uniformly from zero to its maximum value at mid-height (1.4m) in 7.5s and then decreases uniformly to zero in 7.5s. The peak power output is 6kW when the velocity is maximum, determine the maximum lift force provid..
A turbine disk made from a Ni-base superalloy will be operating at 1350F. The creep data are given below. Determine the maximum stress allowable if the design criterion requires less than 1% strain in 10,000 hours.
The Bode plot of shaft vibration of a turbine obtained during coast-down is shown in Fig. 10.44. Determine the damping ratio of the system when the static deflection of the shaft is equal to 0.05 mil.
A 110 kg machine is mounted on an elastic foundation with stiffness of 2106 N/m. To determine the damping that the machine is subjected to, an external harmonic force of 1500 N magnitude is applied to it at a rate of 150 rad/s. The vibration of the m..
Calculate the required length of splice. Find the hook development length ldh required for a 180° hook in the footing.
