Mass and axle* A mass m is connected to a vertical revolving axle by two strings of length l, each making an angle of 45? with the axle, as shown. Both the axle and mass are revolving with angular velocity ω. Gravity is directed downward.
(a) c
(b) Find the tension in the upper string, Tup, and lower string, Tlow.
air flows through a convergent-divergent nozzle from a large reservoir in which the pressure and temperature are
Derive the expression for a simple spring mass system equation and its response. Plot the response for 3 different values of k, (k=1, k=10, k=100) assume mass M= 1, what are the natural frequencies in rad/sec and Hz for each case. Explain the differe..

What is the order in which the following compounds would be eluted from an HPLC column containing a reversed-phase packing?
Compare these values with the sizes where a maximum occurs in the corresponding distribution curves.
Two collars C and D move along the vertical rod as shown. Knowing that the velocity of collar C is 50 in/s downward, find the instant centers of all three bars, the angular velocity of AB, the velocity of collard D.
A refrigerator uses a R-134a as the working fluid and operates on an ideal vapor-compression refrigeration cycle between 0.12 and 0.7 MPa. The mass flow rate of the refrigerant is 0.05 kg/s.
Generate a first- and second-derivative curve for these data. 43 Does the volume at which the second-derivative curve crosses zero correspond to the theoretical equivalence point? Why or why not?
On which of these systems would you expect slip to ?rst occur as the applied stresses increased? Assuming slip on that system, determine the ratios of the strains, ε2/ε1 and ε3/ε1.
