Q1: 2. A cam, with a minimum radius of 25 mm, rotating clockwise at a uniform speed is to be designed to give a roller follower, at the end of a valve rod, motion described below : 1. To raise the valve through 50 mm during 120° rotation of the cam; 2. To keep the valve fully raised through next 30°B 3. To lower the valve during next 120°; and 4. To keep the valve closed during rest of the revolution i.e. 90° ;See Answer
Q2: The Fink truss supports the wind loads shown. Determine the force in each member and indicate if the members are in tension or compression. Approximate each joint as a pin. Ex=4000cos60=2000lbs.(left) sumMe=20000/(10cos30)=Ay=2310lbs(up) Ey=-4000sin60+2310=-1090lbs.(down)See Answer
Q3: If the box on top of this scissor lift weighs 50 N what is the required horizontal force at P to maintain equilibrium? Disregard the weight of the members and platform. Theta equals 37 degrees and 1 =2 in length, 2L= 10 m. d= 6 m. Hint: Draw four FBD and solve for the unknowns.See Answer
Q4: Examining the front planar truss of this bridge, how many zero force members are observed? Number the members 1 through 21. If the right side of the truss is supported by a rocker and the left side is supported by a hinge, list the members that can be inspected for tension or compression? If a 500 lb load was applied downward on the pin between the green star and the blue box,determine the force in the upper left horizontal member (orange arrow), and the two members directly below (purple pentagons).See Answer

Q8: A ball is swung in a vertical circle at the end of a string. Assuming that the total energy of the ball-Earth system remains constant, show that the tension in t he string at the bottomis greater than the tension at the top by six times the weight of the ball. Note that the radius ofthe cirde doeN not affect this answer. See Answer
Q9: The diameter of the roller is 20 mm and the diameter of the cam shaft is 25 mm. The displacement of the valve, while being raised and lowered, is to take place with simple harmonic motion. a) Draw the profile of the cam when, the line of stroke of the valve rod passes through the axis of the cam shaft, and b) Determine the maximum acceleration of the valve rod when the cam shaft rotate sat 100 r.p.m. c) Draw the displacement, the velocity and the acceleration diagrams for one complete revolution of the cam.See Answer
Q10: On engineering or graph paper, draw by hand the top, front, and right-side view for each block. Include the respective labels: "Top view", "Front view" or "Side view".Please be consistent with your labeling. Please remember to always submit your work in a professional manner. This is expected in the profession (real world). Hence, please pay attention to the final appearance of your work (Points may be deducted if the student fails to satisfy this requirement): 1) Make sure to align the orthographic projections for each block as discussed in class. 2) In addition, make sure that your orthographic projections are sized correctly.
