Figure P4.53 shows a 1-in. solid round shaft supported by self-aligning bearings at A and B. Attached to the shaft are two chain sprockets that are loaded as shown. Treat this as a static loading problem, ignoring fatigue and stress concentration. Identify the specific shaft location subjected to the most severe state of stress, and make a Mohr circle representation of this stress state.
A compressor receives 0.1 kg/s R-134a at 150 kPa, -10C and delivers it at 1000 kPa, 40C. The power input is measured to be 3 kW. The compressor has heat transfer to air at 100 kPa coming in at 20C and leaving at 30C (i.e. like a heat exchanger). What..
a cutting tool uses a nozzle that generates a high speed jet of liquid water water temperature 20 degc. assume an exit
The reference voltage for a fuel cell at 80°C is Ev= 1.18 V. Assume any losses to be negligible and that the voltage at which it operates is the open circuit voltage; in reality, the voltage would be lower due to the current flow. What is the outp..
block b has a mass m and is released from rest when it is on top of cart a which has a mass of 3m. determine the
Consider a DC motor driving a mechanical load as shown below:)Find the time domain solution for x(t) given the to the applied voltage: ea(t) = 5, t > 0 and in Matlab, plot the function x(t) from t = 0s to t = 10s.
What is the communication time if the local conditions limit spacecraft visibility to elevation angles larger than = 18 degrees?
For longer fibers, the strength is virtually unchanged. Estimate the strength of the bond between the fibers and the matrix.
A timber beam is subjected to a maximum bending moment of 2600 N⋅m.- Calculate the maximum bending stress.- Calculate the bending stress 25 mm below the top surface.
an alluminum ball 0.5 cm in diameter initially at 250 c is dropped into a large tank of fluid with tsat100 c which is
it is fair to assume that the heat rejection from an otto cycle is typically to the ambient at a temperature tmin the
In the sketch of a standard gear shown in Fig. 4.27, the teeth are 20° full depth if the pitch diameter is 120 mm and the module is 5, calculate the radius of the pin which contacts the profile at the pitch point. Compute the diameter DM measured ..
The inlet flow is air at 110 kPa and 20°C, moving at an average velocity of 6 m/s. Estimate the pressure drop across the honeycomb.
