Find the maximum shear stress in a 5 1/2 in-diameter circular saw blade if it runs idle at 5000 rev/min. The saw is 14 guage(0.0747 in) steel and is used on a 5/8 in-diameter. The thickness is uniform. What is the maximum radial component of stress?
Two resistors, R 1 = 100.0 ± 0.2? And R2 = 50.0 ± 0.1? are connected (a) in series and (b) in parallel. Calculate the uncertainty in the resistance of the resultant circuits. What is the maximum possible error in each case?
Air undergoes two processes in series: Process 1-2: Polytropic compression, with n = 1.3, from P1 = 100 kPa, V1 = 0.04 m3/kg to V2 = 0.02 m3/kg Process 2-3: Constant pressure process to V3 = V1 Sketch the cycle on a P-V diagram and determine the work..
Water is flowing into the top of a tank at a rate of 200 gpm. The tank is 18 in. in diameter and has a 3 in. diameter hole in the bottom, through which the water flows out. If the inflow rate is adjusted to match the outflow rate, what will the heigh..

Air enters an adiabatic compressor at 100 kPa and 27°C and leaves at 600kPa and 177°C at a rate of 1800kg/h. Determine the volume flow rate of the air at the inlet in m³/s. Determine the power input to the compressor.
A piston-cylinder device is insulated and contains 0.005 m3 of saturated liquid water at a constant pressure of l50 kPa. An electric resistance heater inside the cylinder is now turned on, and 1800 kJ of energy is transferred to the steam.
