Print Reading for 284 Class Date Name Industry Print Exercise 13-2 Refer to the print PR 13-2 and answer the questions below. 1. For each of the datum references below, check whether the datum feature is used to establish a datum axis, datum plane, or datum center plane: plane or center plane axis or Datum A center plane plane or axis or Datum B center plane plane or axis or Datum C center plane plane or axis or Datum D center plane plane or axis or Datum E 2. Besides true position, what geometric controls are specified on this print? 3. Are the basic dimensions of this print size dimensions, location dimensions, or both? tolerance is applied, as 4. For the four threaded holes not marked "A", a(n) indicated by the double-layer feature control frame. 5. What is the perpendicularity tolerance used to qualify datum feature A? 6. Are there any instances wherein the datum reference is a size feature, allowing it to be referenced with an MMB modifier? 7. There is a small circle on the leader line elbow for one of the feature control frames that has a profile of surface control. What does that circle indicate? Review questions based on previous units: 8. What is the scale of the original print? 9. What is the name of this part? 10. Are there any auxiliary views shown? 11. How many threaded holes are there total? 12. What is the major diameter of the threaded holes? 13. For the two slotted holes shown best in the top view, what are the width and depth dimensions at MMC? 14. In the upper-right corner, outside of the border line near the revision block, what does the number T146479 indicate? 15. What is the overall height, width, and depth of this part? H W D.

State one word problem and solve it wherein the ideal mechanical advantage of a wedge is being solved. Use the formula, IMA = (Length of the Widge) divided by (Width of the Wedge). note: please do not forget to include your solution in solving the problem.

Analyse, using the results, how each component failed and justify how each component’s design could be improved. Figure 1   The 220mm-long bolt was used to fasten one of the engine mount to a supporting structure. In an effort to prevent the bolt from coming loose, the torque-prevailing nut and split pin were utilized to tighten the bolt. The bolt held through an aluminum housing. Due to the reduced stiffness of the fastened parts, the bolt supported a greater proportion of the applied force. The bolt's size necessitated a high tightening torque of 660 Nm (487 Lbft). Since this level of torque could not be achieved with the tools at the time, this torque was not specified. The aluminum's maximum bearing pressure was far exceeded by the bearing stress under the nut's head and face. As a result, there was excessive preload loss due to creep. fan shaft First of all, the fan shaft was required to be made of cold-drawn 1040 or 1045 steel with a yield strength of 586 MPa and the expected…
