A gear reduction system consists of three gears A, B, and C. Gear A starts from rest at time t=0 and rotates clockwise with constant angular acceleration. Knowing that the angular velocity of gear A is 600 rpm at time t=2 s, determine a) the angular accelerations of gears B and C, b) the accelerations of the points on gears B and C which are in contact when t = 0.5 s.
Employing the ideal gas model, determine the change in specific entropy between the indicated states, in Btu/lbmol?ºR. Solve 2 ways: Use the appropriate ideal gas table AND also by using a constant specific heat value.
Derive the dynamic equation for RP manipulation of example 6.5 (Introduction to robotics by Craig)by using newton-euler's dyanamics.
A 7 kg cylinder is attached to a series of two springs in the attached illustration. If the cylinder is released from rest - when the springs are both un-stretched - determine the maximum stretch in each spring.
During the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the work input during this process. R(air)=287j/KgK
What should the diameter of the nozzle outlet be in inches and what is the mass flow rate of steam through the nozzle in lbm/min?
a curved nozzle assembly that discharges to the atmosphere is shown. The nozzle mass is 4.5 kg and its internal volume is 0.002 m^3. The fluid is water. determine the reaction force exerted by the nozzle on the coupling to the inlet pipe.
Find the volume rate of ?ow in AB, the velocity in BC, the velocity in CD and the diameter of CE.
One kilogram of air as an ideal gas executes a Carnot power cycle having a thermal efficiency 50%. The heat transfer to the air during isothermal expansion is 50 kJ. At the end of the isothermal expansion, the pressure is 574 kPa and the volume is..
determine (a) the compression ratio, (b) the cycle efficiency, (c) exhaust temperature, and (d) mean effective pressure (kPa). Draw (e) a P-v diagram and (f) a T-s diagram
Evaluate the effect of the water spray on efficiency (net work out divided by heat input) and net power out per kg/s of dry air coming into the turbine.
