In a region of two-dimensional space, there are three fixed charges: 4 mC at (0,0), -4 mC at (-17 mm,5 mm), and 5 mC at (13 mm,1 mm). What is the absolute value of the net force on the -4-mC charge?
A gas turbine for an automobile is designed with a regenerator. Air enters the compressor of this engine at 100 kPa and 20 C. The compressor pressure ratio is 8; the maximum cycle temperature is 800 C:
The power supplied to the compressor is 2.5 kW. Determine the volume flow rate of the refrigerant at both the inlet and exit to the compressor, in m3/min.
The Load is supported by the four 304 stainless steel wires that are connected to the rigid members AB and DC. Determine the vertical displacement of the 500-lb load if the members were originally horizontal when the load was applied.
