Design a linkage that will give a symmetrical "kidney bean" shaped coupler curve as shown in Figure 3-16 (p. 104 and 105). Use the data in Figure 3-21 (p. 110) to determine the required link ratios and generate the coupler curve with program FOURBAR.
A piston-cylinder assembly contains 2 lbm of water, initially at 100 lbf/in.2 and 400 F. The water undergoes two processes in series: a constant pressure process followed by a constant volume process. At the end of the constant volume process, the te..
a structural member is subjected to combined loading so that the fallowing stress occur at a critical point 100 50 40
A strut CB is guyed back to a wall support through cable BA. Two forces are applied to the concurrent joint at B. Determine the tension in cable BA and the force in member CB for a condition of equilibrium to occur.
Suppose that the duct's square cross-section is 0.3 m by 0.3 m and the effective outside heat transfer coefficient is 5 W/m2K in still air. Determine whether condensation occurs.
A 90 kg pilot ejects from a plane and reaches a steady state velocity of 30 m/s with one parachute open. Neglect any air drag force on the pilot and assume that the air drag force can be modeled as an ideal damper i.e. linearly proportional to the ve..
Assume they test null hypothesis H0: versus H1: Will the engineers decide to use the steel if H0 is rejected? Will the engineers decide to use the steel if H0 is not rejected?
In the parallel network of Figure 5.9 there is no current flowing in either loop prior to closing the switch at time t = 0. Deduce the currents i1(t) and i2(t) flowing in the loops at time t.
consider a solid cylinder of radius r and height h. heat is generated in the solid at a uniform rate of q wm3. one of
R134a flowing at 12 m/s enters a 25 mm diameter tube at a quality of 15%, at 36 0C and exits the tube at 10 bar as a saturated liquid. Determine (a) the mass flow rate of the R134a in kg/s, (b) the velocity of the R134a at the exit in m/s and (c) the..
One lb of air undergoes a power cycle consisting of the following processes: Process 1-2: Constant volume from p1=20 lbf/in2, T1=500 oR to T2=820 oR Process 2-3: Adiabatic Expansion to v3=1.4 v2 Process 3-1: constant pressure compression Sketch the c..
the pistoncylinder contains 0.1 kg r-410a at 600 kpa 60oc. it is now cooled so the volume is reduced to half of the
5 A JFET has Na= 10 19cm -3, Nd= 10 16cm -3, a= 0.1 µm, L= 10 µm and Z= 1 mm. Assume the device is Si with an intrinsic concentration of 10 10cm -3and a relative dielectric constant of 11.8. Assume also that in saturation the square law can be use..
