CECM_Homework 5

Determine the diameter, in inches, of a circular steel rod that could withstand a tensile force of 95,000 pounds? If the steel rod was 3 feet long, how much would it elongate in inches? If the steel rod was replaced with a standard size timber (select structural grade Douglas fir) what size (nominal in inches) would it need to be?  Assume the same direct axial stress in compression and tension.

for this question just sketch what it should look like:

please answer question 7

many hours did the carpenter work on the job? 6. What is the area of a rectangular floor that is 7'-3" long and 4'-2" wide? 7. There are 15 risers in a set of stairs running from the basement to the first floor. Each riser is 7 1/4" high. What is the distance between floors? 8. The distance between two floors is 9'-0 1/2". If 14 risers are to be used in a set of stairs, what is the height of each riser?

LESSON: AUTODESK AUTOCAD Choose from the choices:

1.) A ladder rests against a vertical wall at a point 15 ft. above the floor. The angle formed by the ladder and the floor is 71°. Sketch the system described above and answer the following, expressing your answers with 3 significant digits. a. What is the length of the ladder? b. How far from the wall is the foot of the ladder? c. What is the angle between the wall and the ladder? d. What are (a) and (b) in meters?

Question 17 Use basic drawing instruments (pencil, scale, protractor, compass, etc.). Using a free-hand sketch, convert this isometric projection to orthographic projection:

The length of a ribbon is 1.28 m. The length of a rope is 2.74 m longer than the ribbon. What is the length of the rope?

Question 3 You are working on a design team at a small orthopaedic firm. Your team is starting to work on a lower limb (foot-ankle) prosthesis for individuals who have undergone foot amputation (bone resection at the distal tibia). You remember hearing about "osseointegration" in an exciting orthopaedic engineering class you attended at Clemson, so you plan to attach the foot prosthesis using a solid metal rod inserted into the distal tibia. You think stainless steel or titanium alloy might be a useful rod material. You decide to begin this problem by identifying typical tibial bone anatomy and mechanical behavior (as provided in the tables and image below). You assume the tibial bone can be modeled as a hollow cylinder of cortical bone, as represented in the image. You anticipate the length of the rod will be 1/2 the length of the tibia. Q3G: Critical Thinking: What would you propose to your team as the next step in this analysis? Is it reasonable to assume the rod will experience the…

Case Study: Paula’s Pain Paula has worked for Brindle Corporation for 3 years.  During this time, she has worked as a machine operator/cell leader in various work cells.  Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months. Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel.  These tubes get a hole punched in them, a flange welded on, and burrs ground off.  The pipe then gets placed into a gage to check that it was made correctly.  (The tubes weigh about six pounds.) Paula has been performing the welding operation.  She leans into the machine and loads the part into a fixture then positions the flange.  Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons. The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position…
