Design a double-dwell cam to move a follower from 0 to 2.5 in. in 60°, dwell for 120°, fall 2.5 in. in 30°, and dwell for the remainder. The total cycle must take 4 sec. Size the cam for a 1-in. radius roller follower considering pressure angle and radius of curvature. Use eccentricity only if necessary to balance these functions. Plot both these functions. Draw the cam profile. Repeat this for a flat-faced follower. Which one would you use?

Design a cam for a rise-return-dwell (RRD) application using the
fourth order polynomial. The position, velocity, and acceleration
should be zero at the beginning of the rise h, and the velocity
should be zero at the end of the rise.
Plot s, v, a, and j profiles for BOTH fourth and fifth order
polynomials using EXCEL.
(Note: this is to all be done by hand in regards to the fourth
and fifth order polynomial. Only Excel can be used for...

Use Excel to generate a column of x values from 0 to 2.5 in
steps of 0.05 (that means your column must have numbers like 0,
0.05, 0.1, 0.15, . . . , 2.5).
Plot the PDF f(x) on your computer screen for the different
values of x mentioned above for the following distributions.
(a) Uniform (use A = 0 and B = 2.5)
(b) Exponential (use mean = 2)
(c) Gamma (use parameters 1.7 and 1.2)
(d) Normal (use...

Design a system to move 100 gpm of water from a river with
surface water elevation of 201.35 ft msl to a tank with surface
water elevation = 246.55 ft msl. The tank is pressurized; the air
pressure in the tank is 60 psig. The total length of pipe is 125 ft
with 6 standard elbows all made of Sch 40 steel pipe. Your design
should specify the nominal diameter of pipe (use only commercially
available sizes) and the power...

A pipe is carrying liquid at 60 degrees C, that fluctuates in
pressure from 0 to 60,000 kPa (non-capped). The inside diameter of
the pipe is 20 mm and the wall thickness is 1 mm and is made out of
1095 carbon steel, has a yield strength of 813 MPa and an ultimate
tensile strength of 1260 MPa. Using the "Modified-Goodman" failure
criteria and a reliability factor of 99%, determine the number of
cycles till failure on the inside wall....

Design and implement a sequential circuit that counts from 0-3
in a repeating cycle with two inputs: step and reset. If the step
input is 1 the count progresses to the next value, if 0 you stay at
the current value. If the reset input is 1 the count returns to 0,
if 0 it has no effect. If both step and reset are 1, reset takes
precedence.
